The Endless Quest for Effective Rust Prevention-  Automobile Rustproofing-Truck & Car Undercoating


In a world where water and oxygen are common, most useful metals have long since been turned into oxides. We have built much of our technology by wresting these metals from the ground and refining them into their pure forms. Nature is relentlessly turning them back to the way they were. A 400 Billion dollar per year problem tends to get your attention. Especially when you are a contributor and there’s no simple nor easy solutions for Automobile rustproofing & Truck Undercoating

Your car — an investment second only to your home (unless you’ve paid college tuition) — is rotting out from under you.


When Neil Young sang ”Rust Never Sleeps,” he might as well have been croaking about the slow but inevitable deterioration of New England automobiles. Because the states use salt on its roads, vehicles can decline from showroom beauties to embarrassing rust buckets in a hurry.

Automobile Rustproofing -Truck Car Undercoating began as a major business in the 1960s , 1970s and 1980s, when body panels and floors started rusting through after only a few years, largely due to the increased use of road salt. I still remember Rusty Jones  car & Truck undercoating automobile rustproofing commercials, virtually every vehicle sold, purchased an automobile aftermarket auto rustproofing package. The industry for the most part does not exist today, where did it go? Everyone has a theory and I have my own.The bottom line is that it’s still a big problem in desperate need of a solution. We started our business out of a garage next door to our home. My family and I reside in the small country town in New Hampshire .We live on a dirt road, a mile and a half in any direction, couldn’t find us with the GPS if you try.

When I say started the business, (Auto Rustproofing)-(Truck Undercoating)I mean we installed a four post lift, continued doing my own vehicles then offered to help friends and neighbors. I’ve been oiling my truck for years, since my fourth generation Yankee neighbor showed me the results of oil Truck Undercoating  his vehicles. Story goes that farmers noticed the lack of rust on their farm tractors were oil leaks happened. They would broadcast their used motor oil on all the metal surfaces and boom they had a solution. Not only to stop rust, but utilize what would be useless engine oil. I In years past it was common to spread engine oil on dirt roads to hold down the dust, a practice that would surely be frowned upon today. Automobile rustproofing-Truck Undercoating the old fashion way!

Why you need Automobile rust proofing-Undercoating for Trucks

Today, chloride salts are among the most widely used dust suppressants. They work by pulling water from the atmosphere and binding it to road dirt. Calcium and magnesium chloride are the most popular. Sodium chloride, or table salt, is less effective. Chloride salts are very corrosive to metals and can also result in slippery coatings on the road surface. After initial application, yet another follow-up treatment at a lower rate is usually needed to ensure long-term dust control. Yup another contributing factor to the growing corrosion problem for vehicles today. The Automobile Rustproofing-Truck Undercoating industry is about to rebound and why you need to be proactive.

Fortunately, today’s automobile rustproofing- oil-based products (Truck-Car Undercoating) are environmentally friendly and advanced technology makes them highly effective. NHOU (no drip) is formulated to stick around, to remain in place and provide protection in ambient conditions.The technology is still fairly simple to understand. Many of you are familiar with WD-40. In 1953, a fledgling company called Rocket Chemical Company and its staff of three set out to create a line of rust-prevention solvents and degreasers for use in the aerospace industry.

Working in a small lab in San Diego, California, it took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40® -which stands for Water Displacement perfected on the 40th try—is still in use today.

The most interesting piece of WD-40®‘s history is the way in which they came up with the name, considering consultants today are paid tens of thousands of dollars to create catchy names and decorative packaging. Water displacement, that’s exactly what you want your oil to do when applied to the undercarriage of your vehicle. It’s hard to be 100% certain the body cavities, cracks and seems are not holding moisture. When we apply our NHOU , we’re confident that if moisture is present, our oil has the ability to displace it away from the base metal.

In the process, the oil cuts off all oxygen, while forming a protective barrier. Once you remove oxygen, or moisture from the equation, oxidation can no longer occur. This is why I believe oil-based rustproofing (Truck- Car Undercoating) to be the most forgiving approach towards fighting corrosion. Trapping in moisture is in part my theory why automobile rustproofing the conventional way (hard asphalt products) failed.

Thousands of vehicles come through our shop every year, we have yet to see a brand-new vehicle come in completely rust free.

While rust can be categorized into mechanical and superficial, rust is an absolute killer in terms of resale value. Cars with rust are practically untouchable, especially in places with snowy weather that use salt on their roads. Automobile rustproofing- Truck Undercoating prevention is always cheaper than cure, and your car is no different.

Auto Corrosion

While rust (auto corrosion) can be categorized into mechanical and superficial, rust is an absolute killer in terms of resale value. Cars with rust are practically untouchable, especially in places with snowy weather that use salt on their roads. Prevention (Truck & Car Undercoating) is always cheaper than cure, and your car is no different.

For all the talk of modernizing and reinventing the auto industry, of car manufacturers using high-tech materials to make lighter and stronger vehicles that are safer and more fuel-efficient, the majority of the mass-produced automobiles are still the same as it has always been: steel. The modern car still contains more of it than anything else, about 60% by body weight. Aluminum has been steadily taking away market share, but still accounts for only about 8 percent of the weight of a typical car.

The fact is, a new vehicle is subjected to thousands of spot welds and numerous bends and folds during production.
This process damages the pre-coated metal, allowing exposure to the corrosion process. Besides cosmetic damage,corrosion also weakens a vehicle’s structural integrity and can affect steering and suspension components.


Fuel efficiency in the United States must roughly double by 2025 to 54.5 miles per gallon. To achieve this, automakers are targeting the car body/frame, which results in thinner metals.

Living in New England my whole life, I’ve come to loathe rust with a passion that borders on psychosis. Fighting it is a never ending battle, all you can hope to do is slow it down once it’s started. The corrosivity of the local environment will strongly affect the corrosion performance of the vehicle. Here are the 21 states (plus one district) that you’ll almost always see listed as part of the “salt belt”:

Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin and Washington D.C.


Neither one of these is 100% accurate, but both are pretty close.



“The biggest threat salt poses to a vehicle is rust, which is accelerated by repeated exposure to salt. Rust on certain parts of a car can create a slew of problems ranging from hydraulic brake system leaks to subframe damage.” —

One would think with all of the exciting and modern features available on a new car, that  automobile rustproofing or Undercoating or Trucks & Cars would be included. However, the truth is that automobile rustproofing is considered an after-market service, not normally included with a new car purchase.

When you throw into the equation Road brines, that wants to eat through your car like a school of hungry piranhas, not even aluminum can withstand there corrosive effects.

In most states, brine is a mix of rock salt (sodium chloride) and magnesium chloride, dissolved in water so they can be sprayed on the road. “That’s a very important point, because magnesium chloride is much more corrosive than sodium chloride, the rock salt. Many states using this product are facing legal action by common carriers who claim the product is prematurely destroying their vehicles. Brine, which is used to pre-treat roads in the hope that snow will melt on contact, gets into cracks and crevices in which a chunk of rock salt can’t lodge. It’s both cheaper and more effective. Design to stick to the road, does not discriminate when your vehicle travels over it. Thinking of moving to Arizona yet? No Need if you have NH Oil Undercoating for Trucks & Cars

Automobile Rustproofing

In the mid 90s American consumers, businesses, and government organizations own more than 200 million registered vehicles. Assuming a value of $5,000 for each vehicle allows an estimate that Americans have more than $1 trillion invested in their motor vehicles, making our automobiles one of the largest investments collectively among Americans.

If left unchecked, auto corrosion can turn a sleek shining new car into an ugly scattered hulk. Worse yet, it can kill. Rust can damage the steering components in the exhaust system of an automobile causing them to malfunction. It also can reduce the structural integrity of a car. Auto corrosion can begin on the surface of unprotected metal car parts but, more often than not, it does its dirty work beneath the surface, sight unseen. It can start almost anywhere in a vehicle, but especially in areas where two different metal pieces are joined. It can, for example, attack the inside of the doors.


All it takes is for a little water to leak into the seam between a car’s windows and door frames. It can invade the trunk or metal fenders whenever moisture accumulates beneath these parts or when something as simple as headlamps or taillights loosen from their fender mountings to allow moisture to seep in. It can also start within the roof, could, sides or even undercarriage when the paint or other coatings designed to protect these parts are penetrated by corrosive materials or by shop pebbles kicked up by passing cars and trucks.

Often the telltale signs of auto corrosion begin to appear only after weeks or even months of incubating beneath the surface. A car owner becomes aware he or she has rust problems only after noticing the distinctive reddish-brown speckles or flakes of metal beginning to protrude through the paint. At first the specs or flakes may be no longer than the head of a pin. But left unchecked these perforations can spread, engulfing the entire body. Eventually the corroded spots of metal on a car can become so thin and soft that a pencil or even a finger can easily penetrate them.

NH Oil Undercoating® for Trucks & Cars is designed to create a barrier that can’t be broken, chipped or cracked. By staying fluid, our environmentally friendly petroleum-based rust protection heals back over after any abrasions providing lasting protection, even in extreme conditions.

NH oil undercoating over conventional rubberized undercoating cars and trucks

  • Firstly, NH Oil Undercoating® penetrates welded seams, crevices and provides excellent protection for these corrosion-prone areas. Sealants are not as effective in protecting these vital areas.
  • NH Oil Undercoating® does not require shiny clean metal surfaces for good adhesion and is effective on both used and new vehicles. While Rust Check will not reverse existing corrosion damage, it will drastically reduce its progression.
  • NH Oil Undercoating® is a unique none conductive electro-chemical compound that contains Self-Healing Properties.
  • NH Oil Undercoating®  dispels moisture trapped in seams and crevices; “Sealants” usually trap moisture in these corrosion-prone areas.
  • NH Oil Undercoating® “Unlike Sealants” is non-drying; it remains mobile and will never dry, crack or peel.

       *  NH Oil Undercoating®  lubricates as it protects against corrosion.

  • NH Oil Undercoating®  “Unlike Sealants” does not contain any offensive odors or potentially toxic petroleum solvents.
  • NH Oil Undercoating® will not damage painted surfaces and any over spray can be easily cleaned off.

       *  NH Oil Undercoating®  is completely reapplied each and every year to maintain a high on-going level of protection. “Sealants” usually are just inspected or touched-up.

One of the reasons I consider NH Oil Undercoating oil-based Automobile rustproofing Undercoating for trucks & cars is the most effective way to combat corrosion, is its chemically engineered to creep and penetrate into all the seams and spot welds of your car’s body cavities. If moisture is present, it will displace the moisture and create an effective barrier to the surface. When you remove moisture and oxygen you effectively stop oxidation dead in its tracks. Oil has the ability to do both, and if you have a corrosion inhibitor present as is in NH Oil Undercoating, you can combat corrosion on a chemical level simultaneously.

We are convinced that oil based automobile rustproofing is the most forgiving way to treat rust. Conventional undercoating rubberized or paints; only trap moisture and allow the process to accelerate beneath the surface. We need only look to our Canadian neighbors, who have been using oil-based rustproofing maintenance to combat corrosion for almost 40 years. There are several companies offering this type of Undercoating for trucks & cars treatment, some of them undercoating over 250,000 vehicles per year.

Automobile rustproofing-undercoating for trucks & cars has changed over the years, but the concept is basically the same: keep moisture away from metal to prevent corrosion. Depending on your vintage, you might recall a time when people used motor oil as an undercoating. The principle was good but such practice could compromise electrical components of the car as well as be extremely messy.

Used motor oil contains numerous toxic substances, including polycyclic aromatic hydrocarbons, which are known to cause cancer. In addition, tiny pieces of metal from engine wear and tear, such as lead, zinc and arsenic, make their way into lubricants, further contributing to the polluting potential of used motor oil. Motor oil is exposed to heat and oxygen during engine combustion, which changes its chemical makeup. Detergents and solvents are detrimental to the rubber bushings, gaskets, and seals on your vehicles undercarriage. Because spent motor oil is heavy and sticky, and contains an extensive concentrated cocktail of toxic compounds, it can build up and persist in the environment for years. Not to mention the fact that it is illegal!

What is a high salt diet costing you?  Much less if you’re undercoating your cars and trucks!
