Toxic is Cheap. NHOU is Smart! Thinking About Coating Your Vehicle with Used Motor Oil? Think Again. Used motor oil might seem like a cheap solution—but the hidden dangers far outweigh the savings. Toxic Composition: Used motor oil is a hazardous cocktail. It contains polycyclic aromatic hydrocarbons (PAHs)—known carcinogens—as well as heavy metals like lead, zinc, and arsenic. These contaminants result from engine wear and high-heat exposure during combustion, fundamentally altering the oil's chemistry. Environmental Hazard: This thick, sticky substance doesn’t just wash away. It clings to surfaces, builds up over time, and can persist in the environment for years, posing serious risks to soil, water, and wildlife. The infamous "drip, drip, drip" becomes an ongoing source of contamination. Damage to Your Vehicle: Used oil contains detergents and solvents that can deteriorate rubber bushings, gaskets, and seals. Instead of protecting your undercarriage, it could accelerate corrosion and degradation. 👉 Find a factory-trained dealer: nhoilundercoating.com Used Oil is Toxic.

Why We Developed NHOU Boss Wax® Hybrid: Real-World Problems Need Real-World Solutions 🚨 New Truck, Early Rust. A customer recently posted this image of a brand-new $71,000 Ford F-150 with less than 100 miles on it — already showing significant surface rust underneath. It had never even seen salt. This isn’t a one-off case. It’s a reality many vehicle owners face due to prolonged part storage and manufacturing conditions. This was one of the key moments that pushed us to innovate. NHOU Boss Wax® Hybrid: Born from Experience, Not Theory 🛠 From Our Garage to Yours With thousands of vehicles passing through our shop every year, we don’t just sell rustproofing — we live it. Like many of you, we were tired of temporary solutions and wanted a permanent answer. That led us to develop NHOU Boss Wax® Hybrid, a solution designed to meet the demands of new vehicle owners. 🧪 Creeping Technology That Works Before it cures, NHOU Boss Wax® Hybrid creeps and migrates up to 2 inches, displacing moisture and oxygen where corrosion begins. It takes months to fully cure, allowing for deep penetration and comprehensive coverage. 💡 No Need to Remove All Rust The idea was simple: If we couldn’t practically remove every bit of rust from new vehicles, we’d develop a product that made that unnecessary. Our formulation is designed to encapsulate existing surface rust and prevent it from advancing — all while forming a durable, long-lasting protective barrier. More Than a Product — It’s Peace of Mind Whether you're taking delivery of a brand-new truck or maintaining a beloved daily driver, NHOU Boss Wax® Hybrid gives you confidence that your vehicle is protected for the long haul. ✅ Trusted by pros. Tested in our own shop. Backed by experience.
🔥 COMING SOON 🔥 The Rust Revolution is here. We've taken the best of petroleum, lanolin, and wax to create a hybrid product like no other. Engineered from experience, tested in our shop, and built on what YOU told us you wanted. Get ready for innovation that doesn’t rust. 💪🛡️ #RustProofRevolution #HybridProtection #NHOU #ComingSoon #innovationthatdoesntrust
RUST TRIVIA TUESDAY! How much money does rust damage cost U.S. drivers every year? A. $5 billion B. $15 billion C. $23 billion D. $50 billion Hit the comments with your guess—we’ll drop the answer (and a tip to avoid it).
-------Where Farmers’ Wisdom Meets Modern Engineering 🚨 Irrefutable, undeniable-Visual Proof That Oil-Based Rustproofing Works This truck tells the story better than words ever could. It's rusted out—except for one surprising area: where an engine oil leak had coated the chassis. When I started NHOU, local farmers shared stories that shaped our mission. Long before commercial rustproofing, they discovered that oil leaks prevented rust. Many used spent motor oil on their frames—a practice that sparked an entire industry. ⚠️ Important Note: While that method is now illegal and harmful to the environment, it inspired us to act. At the time, there were only generic off-the-shelf products not designed for this purpose. That’s why we pioneered one of the first oil-based rustproofing engineered specifically for vehicle protection—safe, effective, and built for the job. Innovation that doesn't Rust 🎥 Big thanks to JR, one of our passionate authorized applicators, for capturing this incredible real-world proof. JR? He shows up with purpose. Because he knows that behind every vehicle is a story—a hard day’s work, a weekend adventure, a legacy you're building. And that vehicle deserves protection that goes deeper than the surface. 🎥 In this video, you’ll see more than a product. You’ll see a man who treats every vehicle like it’s his own. You’ll see passion, precision, and pride. JR isn’t just applying undercoating. He’s giving your truck a fighting chance against rust 🔧 Protect what you drive. Trust the original. Trust NHOU. #RustProof #NHOU #OilBasedRustProofing #IndustryPioneers #ProtectYourRide #BeforeItRusts

Community, Character, and a Cause That Matters 🇺🇸🐾 We’re proud to stand alongside people like Nick from New England Rust Stoppers, one of our authorized applicators and a member of the Fallen Saints MC—a motorcycle club with a mission. Nick and his crew recently teamed up with Mission Working Dogs, a nonprofit committed to training service dogs for veterans and first responders. Nick donated his time—and with the help of his friends, materials we were honored to provide—to rustproof vehicles and raise funds to help place a working dog with a veteran in need. We were fortunate to contribute a bit more to help that mission succeed. These are the kinds of people we get to work with. Hands-on, heart-forward, and rooted in service. 👉 Join us Saturday, June 8th at our Chichester, NH facility for a cookout and networking event! Members of the Fallen Saints and Mission Working Dogs will be there with a table set up, sharing more about what they do. All donations that day will be matched by NHOU®.

🔧 Why Oil Matters — Just Like in Your Kitchen Ever owned a cast-iron skillet? If you have, you know this: leave it unprotected, and it rusts. But add a thin layer of oil and some heat—and boom—you’ve got a glossy, non-stick, protected surface that lasts for decades. Now think about your vehicle’s undercarriage. It faces salt, water, grime, and road debris daily. And like that skillet, bare metal doesn’t stand a chance without protection. 👎 No oil? Corrosion sets in. 👍 Oiled surface? The rust stops in its tracks. That’s where NH Oil Undercoating® steps in. It creeps into every crevice, clings to metal, and creates an active moisture barrier, keeping corrosion at bay—just like seasoning protects your skillet.

A product that meets and exceeds military specs. ✔️ Abrasion resistance 3X beyond military standards ✔️ Creeps and migrates up to 2 inches into seams and folds ✔️ Displaces moisture and oxygen instead of trapping it ✔️ Allows moisture/oxygen transmission for up to 3 months—preventing rust incubation under the surface 🔒 Permanent, Professional, Protected Available only through trained applicators, Boss Wax® Hybrid comes with a lifetime warranty.

Just Because It Looks Protected… Doesn’t Mean It Is At first glance, both of these steel wool pads seem fully protected. But when we cut one open, we found the truth hiding beneath the surface. The pad on the right was coated with a thick, glossy lanolin wax product. Here’s the reality: Durability means nothing if penetration fails. Most viscous coatings are built to resist abrasion but lack the ability to creep and migrate—leaving seams, folds, and spot welds exposed where rust actually begins. We’ve seen this story before—and that’s why we decided to write a new one. 🧪 Our next-generation product, coming June 7, 2025, doesn’t compromise. It delivers powerful surface durability and deep penetration, protecting your vehicle where it needs it most. 💥 This is more than a product. It's the next evolution in rust protection. Innovation that doesn't rust! Stay tuned. #TheNextGenIsComing #NHOU #RustProofing #VehicleProtection #CreepMatters #BeyondTheSurface #June7 #NewProductReveal #PenetrateAndProtect #innovationwithoutcompromise

The #1 reason most people ignore rust? They don’t see it—until it’s already done the damage. That’s why NHOU protects what you can’t see. Because the cost of waiting isn’t measured in dollars. It’s measured in safety, value, and regret. #PreventDontRepair #NHOU #RustPrevention

Prevention is an Investment. Not an Expense. The People Who Use the Product Know It Best. NHOU isn’t just sold by our dealers—it’s used by them. They trust it on their own vehicles. They believe in the formula. They’ve seen what corrosion does when you wait too long, and they’ve seen what happens when you do it right. ✅ Real protection. ✅ Real results. ✅ Real people who care. #NHOUDealers #WeUseWhatWeSell #RealRustPrevention Rust steals value slowly—and permanently.
🛡️ Rust Starts Where You Can’t See It… But We’ve Been Stopping It Longer Than Anyone. Your vehicle’s undercarriage hides 4,000 to 6,000 spot welds, folds, and seams, which are the perfect breeding grounds for corrosion. And when rust starts in these hidden cavities, coating the surface just isn’t enough. At NHOU Oil-Based Rustproofing, we don’t just claim to know rust—we’ve been pioneering oil-based rustproofing in the U.S. from day one. With the longest documented track record of success, we’ve proven what works... in the real world, not just in our lab. We back it up by protecting over 3,000 vehicles a year in our own shop, while our 250+ certified franchisees and dealers apply it nationwide. Because the best product is useless if it’s not applied by trained hands. Period. That’s why we created NHOU: ✔️ Penetrates deep into spot welds and hidden seams ✔️ Displaces moisture and oxygen—the root of rust ✔️ Shields with an unbeatable barrier against brine, salt, and road chemicals ✔️ Backed by the pioneers of oil-based rustproofing in America Protect What You Can’t See.

🚗 THINK YOUR CAR WASH IS HELPING? IT MIGHT BE MAKING THINGS WORSE. During winter, most car washes use filtered water — but even they admit it can’t remove salt. In fact, you may be blasting salt-laced water into the hidden areas of your undercarriage, forcing corrosion deeper into the seams of your vehicle. 📉 The result? Accelerated rust. 🔗 Read the article https://www.chicagotribune.com/2018/03/25/readers-urge-for-clarification-on-salt-water-in-car-washes/?fbclid=IwY2xjawKP6thleHRuA2FlbQIxMABicmlkETFkdG9pVzdnMFZlbGxrOVJFAR5wuvQUX6lprA_GTbWcRoxIYEAq4m0I3cMiOFdBX_AAmZmp7VwpYMZBjZmXOQ_aem_rY8oNNBqmbwv1xmoDRMwjA 🌱 WHY SPRING IS THE TIME TO ACT Winter salt doesn’t just wash away — it settles into body cavities, seams, and frame rails, especially in vehicles that haven’t been protected. Then spring arrives: Cool nights and warm days create condensation. Moisture activates the salt. Rust accelerates — fast. 🛡️ THE NHOU® SOLUTION At New Hampshire Oil Undercoating®, our oil-based rustproofing penetrates deep into your vehicle’s seams, displaces moisture, and neutralizes corrosive salt—providing essential protection even in hard-to-reach areas. 📆 Spring and early summer are the best times to treat your vehicle — before rust from winter takes hold. 💥 TAKE ACTION BEFORE RUST DOES ✅ Rustproof your car ✅ Protect your investment ✅ Drive with peace of mind 👉 Book now: www.nhouoilundercoating.com #RustProofing #NHOU #SpringMaintenance #SaltKillsCars #UndercoatingSeason #TruckLife #ProtectYourInvestment #CarCareTips
