Years ago, the owner of this truck made a decision. It costs time. It costs money. One day, someone else will own this truck. They may never meet the person who took care of it. But they’ll benefit from every decision that person made. Responsible ownership creates value! That’s Steward. #Steward #Stewardship #ResponsibleOwnership #OwnershipMatters #RealValue
Salt does not care that your vehicle is a 2026. Given the opportunity, it will eat it anyway. This video from Scott is a perfect Rust Belt reality check. His brand new truck on the lift. Thick salt stuck everywhere. Frame, seams, body. That white crust is not cosmetic. It’s chemistry doing what it does best. Oil undercoating works because it stays wet. It creeps. It pushes moisture and salt away from the metal instead of sealing it in. Done right, it can add 10 to 15 years of usable life to a vehicle that would otherwise rot from the inside out. Huge thanks to Scott for showing this and for the plug. New truck. Old problem. Same solution. Rust doesn’t need time. It just needs salt and opportunity. Optional light humor lines you can swap in or add: • Salt is undefeated. Unless you cheat and oil the fight. • Rust Belt winters. Where your truck ages in dog years. • That’s not snow under there. That’s future regret. • New truck smell fades. Salt damage does not. Protect it before you see it #RustBelt #OilUndercoating #SaltKillsVehicles #RustPrevention #ProtectYourInvestment
Marc, one of our franchise partners, shared this video for a reason. That screwdriver is standing straight up in V3 Hybrid. Yes, it’s thicker than our regular NH Oil. But here’s the part that matters. It still sprays easily. It still penetrates. And it still creeps deep where rust actually starts. V3 was engineered to give you more body without giving up the ability to move into seams, folds, and spot welds. Thick where it counts. Active where it matters. This is what happens when real-world experience drives product development.

This photo marks the beginning of our company. Our first lift. Installed in the garage next to our home. That day, our small town police cruiser was in for service. My son Joey was standing right there with us. Just a normal workday at the very beginning. A lot has changed since then. Bigger shop. Bigger team. Better tools. But the real reason we’re here hasn’t changed at all. Our customers are the heroes of this story. You take care of your vehicles before there’s a problem. You invest time, effort, and money because you see the value in doing things right. That mindset is a big reason we’ve grown. And it’s the reason we’re working on something new behind the scenes. We’re building a project that recognizes and acknowledges people who are responsible stewards of what they own. Because that kind of care doesn’t just add residual value. It’s respected. It’s noticed. And it matters to more people than you might think. We’re not ready to share details yet. Just know this — we’re raising the bar, and it’s built around the same people who got us here in the first place. More to come when the time is right. Thank you for being part of it. Good care doesn’t go unnoticed. #Stewardship #TakeCare #WellCaredFor #DoItRight #BuiltOnTrust #ProactiveCare #LongTermThinking #GoodOwnership
Rinsing is not protection Road brine is not just salty water. It is engineered to stick. When you drive through it the damage does not stop when the road dries. Many people are told to just rinse it off. The problem is where and how that rinse happens. Most professional car washes recycle roughly 80 to 90 percent of their water. According to the car wash industry itself standard reclaim systems remove grit and debris but cannot remove dissolved salt. That salt stays in the water. As industry professionals have pointed out, rinsing with reclaimed water can actually push salt laden moisture deeper into seams boxed frames and body cavities where it sits and works nonstop. This is why we focus on protection that displaces moisture and blocks oxygen, not just washing and hoping for the best. Education matters. Rust never sleeps. And brine does not forgive shortcuts. #RoadBrine #RustPrevention #UndercarriageProtection #SaltDamage #AutomotiveEducation
This is a good example of why equipment and training matter. Oil undercoating is not a spray and pray job. If you are laying on the ground guessing where the wand is pointing, you are going to miss things. A lot of things. Rust does not miss those spots. This is exactly why we do not allow mobile applications unless the vehicle is lifted over your head in a wedge trailer with proper lighting. You need to see the surface to protect the surface. Simple as that. Does a wedge trailer automatically mean a perfect job. No. But if someone invests in the right equipment and takes the time to train properly, odds are they take the work seriously and the customer gets a better result. Rust prevention is about access, visibility, and coverage. The oil only works where it actually lands. And thanks to Scott for putting this out there. Transparency like this helps raise the bar for everyone. If you are shopping for undercoating, ask one question How do they get eyes on what they are spraying #RustPrevention #UndercoatingDoneRight #DetailsMatter #RaiseTheBar #OilUndercoating #TruckLife #ProfessionalNotGuessing
This is very disappointing news to hear. Our business has supported Hillsborough American Legion Post 59 through golf tournaments and events for several years because we believe deeply in supporting veterans and the work these posts do for the community. What one individual did was a betrayal of trust. It does not represent the values of the Legion or the men and women the organization exists to serve. If anything, this moment matters more. Veterans still need support. Post 59 still needs honest leadership and community backing to rebuild trust and move forward. We stand behind the mission. We stand behind veterans. And we hope this post comes back stronger with transparency and integrity. https://www.facebook.com/share/p/17wWPeiH5t/
Low-country trucks live a hard life ou wouldn’t think rust would be a big deal in coastal South Carolina. No snow. No salt trucks. No winter. But when you’re low country, you’ve got a different enemy. Brackish water. Tides. Humidity that never quits. That salty moisture works its way into frames and never really leaves. It’s like the ocean playing the long game on your truck. These before and after photos are from NHOU Low Country. Body off. Frame exposed. This is what rust actually looks like before you ever see it on the outside. Good news. Rust isn’t fast. It’s patient. Better news. So are we. Protect it early. Or wait until the ocean claims it as a reef. Shout out to the Low Country crew for keeping coastal trucks alive a little longer. #NHOU #NHOUlowcountry #AdvancedRustProtection #CoastalRust #SaltAirKills
You remember learning how to use your hands. How to solve problems. How to stand on your own two feet. This country wasn’t built in conference rooms. It was built in workshops, garages, job sites, and places that smelled like oil, steel, and hard work. We believe in the men and women who build, fix, weld, wire, cook, and keep everything running while everyone else talks about it. That belief isn’t a slogan for us. It’s how we operate. And because of that, we’ll be looking for a new rustproofing technician this summer. We’re looking for someone enthusiastic, responsible, and willing to learn. No ego required. Curiosity helps. What we offer: • Good pay • 401k with matching • Top-tier healthcare • Tuition assistance to learn related automotive skills In short, a real career — not a dead-end job. Skills built this country. Working people keep it running. We’re proud to stand with them.
Brand new truck. 100 miles on the title. Rust already on the frame. That is not a defect. That is reality. Modern trucks are built fast shipped far and sit outside. Moisture and salt get to them long before the first oil change. That is why we built Boss Wax Hybrid. It started as a military corrosion prevention system and was adapted for civilian trucks. In some areas it exceeds military performance standards by a wide margin. We did not develop this in a lab and hope for the best. We are the highest volume undercoating shop in the country. We see new trucks every day with surface rust and we protect our own vehicles with the same product. Boss Wax Hybrid creeps and migrates pushing moisture and oxygen out before sealing the metal. It is designed for new trucks and lightly rusted frames especially Chevy and GMC trucks with factory wax coatings. Military-grade protection. Real-world proof. Built for trucks that are already starting to rust the day you buy them. Military-grade protection for civilian trucks #BossWaxHybrid #NHOU #MilitarySpec #ChevyTruck #GMCTruck
These photos are from the early days. A basic cargo trailer. On-site jobs. Heavy equipment. No blueprint. Just problem-solving. Back then, undercoating wasn’t what it is today. There weren’t many people doing it, and even fewer doing it well. What changed everything wasn’t us trying to build a brand. It was customers who needed real protection and were willing to take a chance. Over time, those needs pushed the industry forward. Better standards. Better expectations. Better results. We’re thankful to everyone who played a part in that journey. You didn’t just protect your vehicles. You helped bring something back. Built alongside the people we serve! #BuiltByCustomers #EarnedNotMarketed #FromTheGroundUp #RealWorldSolutions #RustProtection #Undercoating
Prep is protection! This is Marc from our Wisconsin franchise using a frame jet from Rust Crushers. Over time, dirt, dust, and debris build up inside frames and body cavities. You may not see it, but it retains moisture and accelerates corrosion. If your vehicle is more than a few years old, this is a service worth considering. If you live on or drive dirt roads, it’s not optional. It’s just part of proper protection. This is the kind of real-world prep that makes undercoating actually work. #PrepMatters #FrameCleaning #RustPrevention #Undercoating #WorkTruckLife
Rust hates oil Marc sent this one over. Same bumper area. Two different stories. One is rusty. One is oily. Is oil a little messy? Yep. Does it look pretty? Not really. Is the bumper rusted? Also nope. Oil creeps. It migrates. It gets into seams and edges where moisture and road junk love to sit. That’s what stops rust before it starts. https://www.facebook.com/share/r/1a8712teA3/
Today we’re sharing this with heavy hearts. Lonny Meloon was one of our very first customers. Back when NHOU was just us working out of the garage next to our house, servicing neighbors. Lonny was one of them. From day one, he supported us. And he never stopped. He showed up to every public event. He talked about us online constantly. He told people about us before we had anything to prove. Over time, he stopped being just a customer. He became a friend. A familiar face. Part of our extended NHOU family. We’ve always said our customers are our family. As we’ve grown, that hasn’t changed. The relationships matter more than the size of the business. More than money. More than success. Later on, I found out Lonny was a lawyer. When we needed legal help, we chose his firm for the same reason he chose us in the beginning. Character. Yes, he was good at what he did. Yes, he was smart and capable. But character always mattered most to him. And to us. Lonny believed in people. He showed up. He supported small businesses. He stayed loyal. And he did it quietly, consistently, and with heart. We’re grateful for him. We’ll miss him. And we’re better for having known him. Rest easy, Lonny. Thank you for being part of our story.
TRADE SCHOOLS DON’T NEED DEFENDING. THEY NEED RESPECT. This one’s personal. I never fit the box that public education and traditional college had for most kids. I think differently. I work with my hands. I think non-linear. And for a long time, school didn’t know what to do with that. A lot of kids still feel that way. Shop class didn’t just teach tests. They taught how to build, fix, and stand on your own. Shop class built confidence. Working with your hands built pride. Earning skills built a backbone. These aren’t backup plans. They’re essential professions. Skill, discipline, pride, and work ethic built this country. And here’s the part we’re excited about. We’re starting a new venture. It won’t make us money. It’ll probably cost us some. But what it creates matters more than money. We’ve already begun teaching shop classes in public high schools. Hands-on. Real world. No nonsense. We’re also building an entrepreneur program into shop training and traditional trade schools. Because a lot of these kids won’t just learn a trade. They’ll start businesses. That’s how this country actually works. If you’re a shop teacher and want us to come into your school for a hands-on class on: • Rustproofing • Auto body • Welding • Getting into the automotive trades Call 603-491-9012 extension 1. Soon we’ll also be offering scholarships and partnering with a local New Hampshire nonprofit that supports the trades. No kid should feel inferior because they’re wired to build, fix, create, or work with their hands. This is just the beginning. More to come. Stay tuned. #TradeSchoolsMatter #RespectTheTrades #WorkEthic #SkilledLabor #EarnedSuccess #BuildAmerica
Quick update from us. Our V3 Hybrid has officially become our number one selling product. And it didn’t get there by accident. V3 is more viscous than our traditional oil, so you get penetration and abrasion resistance all in one go. If I had to choose between thickness and penetration, I’d take penetration every time. Luckily, V3 gives you both abrasion protection and that deep reach you need. A bunch of folks who used to use super-thick products have switched to V3 and they’re all singing its praises. Designed to penetrate. Built to last. #NHOU #V3Hybrid #AdvancedRustProtection #RealWorldTested
Rust doesn’t hide when it’s documented Here’s a hard truth most buyers never hear. Rust doesn’t show up on the paint. It hides underneath the vehicle. That’s why some sales managers still tell their staff not to let customers look under a vehicle. Or, even more frustrating, they intentionally conceal it with black paint or rubberized undercoating. Not because it doesn’t matter. Because it does. A truck can look great on the lot and be rotting where you can’t see it. And once you own it, that problem is yours. This is exactly why we built Rustfax. Photos and videos of the undercarriage. Documented service history. Time stamped. VIN based. No guessing. No ‘trust me.’ If you’re buying or selling, transparency shouldn’t be optional. Look underneath. Always. #LookUnderneath #Rustfax #vehicletransparency https://www.facebook.com/share/v/1BrhrcnQEz/
End of the year always makes me look back. In 2012, we opened the doors in a small garage next to our house. No big plan. No industry roadmap. Just a belief that rustproofing could be done better and more honestly. What started as a small family operation has grown into something I’m really proud of. New products like V3 and Boss Wax. Teaching kids in trade schools. Scholarships in the works. Better records and transparency for vehicle owners. All of it came from listening to customers and trying to solve real problems. We’re still a family business. Our kids. Our relatives. Close friends. Still getting our hands dirty every day. I’m grateful for the people who trusted us early, stuck with us, and helped shape what this has become. None of this happens without you. Still family. Still hands-on Excited for what’s next. Even more thankful for the journey.
Rust doesn’t show up overnight. But when it does, it quietly drains your vehicle’s value. That’s why Rustfax is coming. Rustfax lets you: Store all your rustproofing and proactive maintenance in your own digital record Track protection before problems start Prove your vehicle was cared for, not just repaired List and search rust free vehicles in our classified marketplace Stand out to buyers and sell with confidence And here’s the big one. You own the record. It stays with you. Not a shop. Not a dealer. Not buried in paperwork. When it’s time to sell, you’re not explaining. You’re showing proof. Rustfax. Because rust free vehicles don’t happen by accident. And smart owners plan ahead. 😏 The future of rust-free resale. #Rustfax #RustFree #ProtectYourInvestment #ProactiveMaintenance #SellSmarter
Merry Christmas and Happy New Year to all of our customers. We’re truly thankful for the trust you put in us. This business exists because of you. Your support. Your loyalty. Your belief in what we do. While things slow down for the holidays, we don’t stop thinking. We’re already working on some new and innovative projects behind the scenes that are all about one thing.

Just a reminder that most NHOU locations, including our flagship shop in Chichester, NH, will be closed for the Christmas break. Please check with your local shop for their exact holiday hours. Chichester will be closing on December 20th and reopening on January 2nd. From our family to yours, we wish you a wonderful Christmas and a happy healthy New Year. We truly appreciate every one of you. Our customers are the reason we do what we do.
Here’s a little something about why we’ve supported Derek Robbie for almost 10 years now. Yeah sure… we love racing. Loud motors. Fast cars. Smells like burnt rubber and happiness. All that good stuff. But honestly? The real reason we jumped into this world is because of the families behind these teams. Mom, dad, kids, even grandparents out there freezing at 6am like it’s a family reunion with horsepower. That’s what hooked us. That’s what we stand behind. We’re a family business too. My kids work here. My brother works here. Half my close friends work here. If this place ever goes “corporate,” someone better check my pulse because that’ll be the day. So Derek — thank you, buddy. Your video today meant a lot. We’re thankful for you, your family, and the whole crew. Hope this partnership keeps rolling for many more years… preferably without any blown engines, but hey, racing is racing. https://www.facebook.com/share/v/1BMqsrY1LT/
Here’s a cool little slice of “garage science.” Marc spotted an old pickup with an oil leak… and guess what? Zero rust anywhere the oil’s been dripping for years. Meanwhile the rest of the truck looks like it survived the Titanic. This is literally how oil-based undercoating started. Farmers saw their tractors staying clean where the oil leaked and said “Huh… that’s interesting.” Sometimes the truth is sitting right there on the shop floor. Oil protects metal. Always has. Always will. https://www.facebook.com/share/r/16SwPEepdY/
Teach the trade. Protect the future. Huge shoutout to Craig from Young Blood Undercoating in Hudson NH. He went out to Salem High School and basically turned shop class into Undercoating 101. The teacher told us a bunch of the quiet, shy kids lit right up once they got to grab the gun and actually spray. Honestly… same. When I was their age, shop class was the only place I could actually see something I built work. Math class never cheered me on like that. We’ve had a bunch of schools ask us to do this, and we’re all in. It’s fun. It’s hands-on. It gets kids thinking about a trade that’s making a legit comeback. And hey… it beats another worksheet. Big thanks to Craig for being a killer brand ambassador and apparently a substitute teacher now. Dude might actually get tenure at this point. #NHOU #RustProtection #Undercoating101 #ShopClassHeroes #TeachTheTrades #FutureTechs #HandsOnLearning #YoungBloodUndercoating #CommunityMatters #RustNeverSleeps #ProtectWhatMatters
Real miles. Real results. Real protection. Sharing this awesome video from JR. His truck has 30,000 miles on it and the factory paint underneath looks brand new. That’s what real protection looks like. We’re not just the pioneers in this industry… we actually use our own products every day and back it with our in-house lab. Proof beats promises. Every. Single. Year. If you want your vehicle to age like this, don’t gamble. Choose the product that delivers results you can see. Protect it now. Thank yourself later. #NHOU #RustProofing #V3Hybrid #Undercoating #RealResults #ProtectYourRide #DoubleDefense #SaltSeasonIsComing #jrapproved
Spring Frame Rescue is coming. If you missed getting your vehicle rustproofed this fall… you’re not alone. Every year we turn away hundreds of people because the fall rush gets insane. Don’t sweat it. We’ve got you covered this spring. We’re putting together a Spring Frame Rescue package built for the folks with older rides, dirty frames, salty winters, and no protection yet. Think deep cleaning, salt brine eliminator, frame flushing, prep work, and a fresh coat of V3… all tuned to bring your undercarriage back to life. Details are coming soon. Just know this: your vehicle’s not too far gone. We can save it. Stay tuned.
“Will NHOU rustproofing void my warranty?” We hear this one nonstop, so let’s clear it up once and for all. No. It won’t. Your warranty is 100 percent safe. There’s a federal law called the Magnuson-Moss Warranty Act. Yeah, sounds like a spell from Harry Potter, but here’s what it means in normal English: A manufacturer can ONLY deny your warranty if they can prove an aftermarket product caused the issue. So unless our oil suddenly grows arms, grabs a ratchet, and starts breaking your suspension (which would honestly be impressive), you’re good. Most dealerships won’t say this part out loud… Rustproofing actually helps your vehicle last longer. Less rust = fewer warranty headaches for them. Now… quick message to our very loyal competitors who follow our page more than some folks follow Taylor Swift: We see you. We know you’re here. We know that “new” post you put out last week looked suspiciously familiar. It’s cute. Really. Bottom line NHOU won’t void your warranty. It WILL protect your investment. And it might educate half the industry along the way. #NHOU #WarrantySafe #RustProofing #LeaderInProtection #NoRustNoBS
Check this out — Marc pulled pounds of mud and debris out of this Chevy frame. That stuff builds up fast, and it traps moisture and salt like a sponge. If you’re just starting to undercoat after a few years on the road, this step matters. Cleaning the frame lets the oil actually reach the metal so it can creep, protect, and do its job the right way. A little prep now saves a lot of steel later. Protect your ride — don’t let the mud do the rusting for you.
⭐ Real Results. Real Protection. ⭐ Huge thanks to Dave for sharing his experience! After 5 years, his Tacoma still looks incredible underneath thanks to our Boss Wax treatment. When it came time to protect his new 4Runner, he didn’t hesitate—he came straight back to NHOU, this time choosing our next-generation V3 Hybrid Clear. Dave’s story says it all: when you invest in your vehicle, you want proven protection that lasts. That’s what we do every day. Ready to protect your own investment from the salty New England roads?

From Our Garage to Napa — Because of You Hard to believe we started this business in the garage next to our home, using off-the-shelf products and never quite satisfied. So we created our own formula for the customers who trusted us with their vehicles. Before long, stores were calling asking to carry it — and in this pic we’re delivering our first load to a Napa store in Laconia, NH. A lot has changed in 15 years, but one thing hasn’t: you are the reason any of this happened. Your trust pushed us to innovate, your feedback made our products better, and your support grew a little garage idea into something much bigger. We’re grateful to live in a country where family businesses can grow by serving their neighbors well. Thanks for being the hero in our story. #ThankYou #FamilyBusiness #SmallBusinessJourney #NapaAutoParts #ProtectWhatMatters #NHOU
They say on a quiet night you can hear a Chevy rust! Chevy Silver-Rust-ado. Funny name… not so funny when it’s your truck. This is what New England winters + salt + zero protection look like. The good news? It doesn’t have to happen to you. For about $300 a year, oil-based rustproofing is the cheapest insurance you’ll ever buy. One visit a year… or one truck in the junkyard. Your call. Keep the truck. Lose the rust. 👉 Protect your investment with #NHOU https://nhoilundercoating.com/ Stop rust before rust stops your truck. #NHOU #RustStopsHere #SilverRustado #RustProofing #ProtectYourRide #NewEnglandWinters #SaltKillsTrucks
Double defense against rust and rodents! Big thanks to Scott over at Flippin Customized for shining a light on a very real New England problem. When winter rolls in the mice start shopping for real estate and too often they pick the warmest condo they can find your vehicle. With soy based wiring harnesses basically turning into gourmet snacks the damage can get ugly fast. Our Mouse Out infused undercoating was laboratory tested to be 92 percent effective at keeping rodents away while still giving you the best protection against corrosion. One product two big problems solved. The only thing we cannot guarantee is that the mice will not leave you a tiny eviction note. Check out Scott’s video and keep your wiring and your undercarriage protected before winter really hits. #NHOU #MouseOut #RustPrevention #RodentProtection #WinterPrep #AdvancedRustProtection #ProtectYourInvestment
Don’t wash rust in. Keep it out! Car Wash Myth Busted--Rust doesn’t care how clean your car looks. Most folks think running through a car wash in winter will save their undercarriage from rust. The truth? It might just be feeding the problem. Eric Wulf, CEO of the International Carwash Association, explained it best: “No, filtration doesn’t remove all the salt… Reverse osmosis is usually not used for undercarriage washing. Most washes use a mix of fresh, recycled and reverse osmosis water… which means that salt is quite diluted.” Translation: the dirt may be gone, but the salt is still along for the ride, only now it’s being blasted at 1,500 psi into every seam, fold, and cavity where rust loves to start. That’s not protection… that’s an express delivery service for corrosion. That’s why we don’t rely on recycled salty water. NHOU products are engineered to creep, migrate, and displace moisture and oxygen in the 4,000–6,000 seams where rust really begins. So yes, get your car washed if you like shiny paint. But if you want it to last? Don’t wash rust in. Keep it out. 👉 Ask about NHOU rustproofing today.https://nhoilundercoating.com/ #RustStopsHere #NHOU #RustPrevention #ProtectYourRide #CarWashMyth #rustproofing
Protecting history one vehicle at a time. There’s something special about bringing a piece of history back to life. This 1950s Mount Washington snowcat was rescued from a scrapyard by Brian, who is now painstakingly restoring it back to its original glory. When the restoration is complete, he’s chosen to protect it with NHOU Oil. That says a lot. A machine built to survive the harshest weather on one of the toughest mountains deserves the very best protection on the market. And we’re honored that Brian trusts our products to help preserve this legendary snowcat for the next chapter of its life. If you appreciate craftsmanship, history, and seeing old iron saved instead of scrapped, you’ll enjoy this video. #NHOU #RustProtection #Restoration #OldIron #Snowcat #MountWashington #ProtectWhatMatters #nhouoil
Family, Faith, and a Little Elbow Grease I wanted to share this great interview with my friend Jim and his son Nate. They run a small cobbler shop — yes, a real shoe repair shop — something you don’t see much anymore. Watching it reminded me how much pride and work ethic still live on in family businesses. Jim and Nate’s story hits home for me. I met Jim years ago through church and our local homeschool group. Our sons grew up together — Joey, Anthony, and Nate — and just like Nate, my boys found themselves drawn into the family business (ours just happens to be a little messier and smell more like oil than leather). In a world of corporations, call centers, and “press 2 to speak to nobody,” something is refreshing about walking into a small shop where you’re greeted by name and treated like family. Family businesses like Jim’s — and ours — aren’t just keeping old trades alive… we’re keeping community alive. If you’ve got a minute, check out their story — it’s a reminder that good people, hard work, and strong values never go out of style. #FamilyBusiness #SupportLocal #WorkEthic #CommunityStrong #OldSchoolValues #madebyhand
If you’ve ever wondered who keeps this place spotless and running like a "well-oiled" machine—it’s Carol! 🎄 She’s the voice on the phone, the one answering texts at midnight, and the reason our waiting room looks ready for Santa himself. So if you stop in and love the clean floors or the Christmas cheer—make sure to tell Carol she’s the real boss around here! 😄 #FamilyBusiness #NHOU #BehindTheScenes #HardWorkPaysOff #ChristmasAtTheShop #ShopLife #TeamNHOU #CarolRocks
