With apologies to Sir Walter Scott, who said “time will rust the sharpest sword,” we say rust will ruin the sharpest car (unless it is made of plastic).
What exactly is Rust and why is it so bad?
Rust is the chemical process of oxygen and water combining with iron (like the steel in your car, truck, van or SUV). When those elements find unprotected steel, they merge forming the brown, flakey material we call rust. Rust corrosion will eventually eat completely through your metal vehicle unless you stop rust.
When you finally decide to buy a new car it is a very exciting day. Although many assets appreciate in value as they age, a car is not one of them. Edmunds estimates that new cars lose as much as 20% of their value as soon as they are driven off the lot. But you have improved your car’s resale value by wisely being proactive with corrosion.
Undercoating / Rustproofing effectively seals areas from the environment, abrasion, and harsh chemicals like road salt. With specialized tools and training, a skilled technician has the ability and knowledge to seal all of the areas of your vehicle that need it and avoid all the areas that don’t. Undercoating / Rustproofing also helps reduce road noise. With yearly maintenance, you can have your undercarriage sealed for years to come!
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.
With the introduction of road brine ( liquified salt ) this extremely corrosive solution is now able to penetrate deep into your vehicle’s body cavities where rock salt could not. Many of these Road brine solutions contain magnesium chloride, calcium chloride and additives to help them stick to surfaces. The problem is, they don’t discriminate.
Did you know early undercoating products were made from chicken fat?! This process was a flop because the high sulfur content made it very corrosive.
Tar and tar-like compounds were a vast improvement and were used for many years, beginning around the 1950’s, but they did little to prevent a vehicle’s underbody from rusting through. As the undercoating dried, chipped and broke away in chunks, water would get trapped between the remaining coating actually accelerating and promoting corrosion.
Undercoating products today contain a range of ingredients including fiberglass, rubber, ceramics, silicone, asphalt, or petroleum. These products offer different benefits but all protect against damage and the elements.
Which undercoating is right for you?
This is a critical step, choose the wrong one you may trap moisture under the coating or the coating cracks in which case water gets under the coating and rusts away which you will not see until you can poke holes through your car.
Unless your vehicle is brand-new and completely rust free you should avoid hard, rubberized single application products. These products are very effective but must be applied to a rust/moisture free surface.
A semihard product like wax which will not crack or chip from Road abrasion works best. A petroleum-based oil should also be applied inside body cavities where rust begins.
Body cavities are prone to hold moisture and the surfaces are unfinished.
The oil should be designed to migrate and creep so that it may go deep into the body cavities, spot welds and seems. The product should have corrosion inhibitors and preferably be a non-drip formula.
Oil works very differently than hard rubberized undercoating. If oil is formulated properly it will displace moisture from the base metal, then cut oxygen off. Take either out of the equation and oxidation cannot occur. Oil is self-healing so it will not chip or crack but will need to be re-applied annually.
Having existing rust may not be a bad thing as it gives the product something to hang onto. If you have existing rust there is a product NH Back N Black that will significantly improve the look of the surface while protecting it. You will also create a barrier against moisture, salt and Road brine which is a vehicle killer.
Undercoating a new vehicle
Should you use a soft oil-based rustproofing product or a one time semi-hard wax based product?
The choice is a personal preference. In most cases if applied properly both will be equally as effective. The upfront cost for a semi permanent wax based product will be significantly more than an annual application of petroleum oil.
Either service should be followed up with regular checkups and maintenance. Keep in mind when you research your options that we cannot beat mother nature, we can only hope to slow her down. Rust has been described accurately by by Jonathan Waldman , Rust: The Longest War It has been called “the great destroyer” and “the evil.” The Pentagon refers to it as “the pervasive menace.” It destroys cars, fells bridges, sinks ships, sparks house fires, and nearly brought down the Statue of Liberty. Rust costs America more than $400 billion per year—more than all other natural disasters combined.
The biggest challenge is cultural more than technological. Getting people to think proactively with corrosion is the biggest challenge. Regardless of which method you choose to battle corrosion, the most important element is that you choose something. NH Oil Undercoating® offers a product Wax N Oil which combines the best of both options. The product is a semi-hard black standalone application. This product on a warm day and a on a very small scale can self heal. It does not collect dirt and dust as oil-based petroleum products do. But is a very effective tool in your battle to extend the life of your vehicle.
What is NH Oil Undercoating®?
NH Oil Undercoating® is designed to slow down or inhibit corrosion on vehicles. It is a petroleum based product with rust inhibitors containing no solvents. In fact the NH Oil Undercoating® product is environmentally safe, contains no toxins or solvents, is non-flammable, is non-reactive, is non-corrosive, can be sprayed in any weather, remains active, and is a nonhazardous unregulated product.
NH Oil Undercoating is a unique blend of highly refined petroleum and rust inhibitors that guard against rust and corrosion on all metals. It eliminates moisture containing salt, dirt and other pollutants from the metal providing long lasting protection for your vehicle.
Penetrate & Lubricate
After NH Oil Undercoating® is applied, you can expect it to lift and remove dirt, moisture, other contaminants and even some surface rust. It is designed to penetrate to the good metal and form its protection there. As it penetrates it pushes out existing moisture and oxygen thus eliminating oxidation-corrosion.
NH Oil Undercoating® stops electrolysis by disallowing the external circuit to be completed. NH Oil Undercoating is designed as a non-conductive material that also has a voltage drop of only 1/100th of a volt. After securing the connections, it can be used on electrical connections to prevent the “greening” of wires.
Active Molecular Protective Film
Once NH Oil Undercoating® has reached the good metal, it sets up a bond. This bond is at a molecular level and the film that is created is ultra-thin providing long-term protection. The inhibitors, meshed together in a chain link, are then used by the environment – contaminants, salts, etc… – before the metal has rusted.
Creeps and Self Healing
NH Oil Undercoating® is designed to creep deep into cracks, crevices, spot welds, seems, folds and provide protection there as these areas up prone to hold moisture and are unprotected. So even if the initial application cannot reach one of these areas, this creeping process assures maximum protection is provided.
Can we improve the appearance if there’s existing rust?
Yes. NH oil undercoating® Back N Black not only protects but it improves the appearance of any metal surface!
