The Best Time to Undercoat and Rustproof Your Vehicle



Rust — as any Neil Young fan knows — never sleeps. There are a lot of things you can do to keep it at bay, though, and get your car through the coming winter unscathed


Vehicles are costly investments. Therefore, it is vital to make sure that you keep them in mint condition. However, this is easier said than done, mainly because of the ever-changing weather and roadside conditions. The external conditions, road chemicals can often wreak havoc on your vehicle by lowering its visual appeal, performance, and even life expectancy. For example, in winter, when you factor in high humidity, road brine, sleet, snow, and rain, your vehicle becomes exposed to rust and corrosion. This is a natural phenomenon that is hard to escape – but not impossible.

Rust is an oxidation process. It attacks your vehicle’s metal when it is exposed to oxygen and water. It is reddish-brown in appearance, which continues to spread. Small spots of rust or corrosion can be spotted in different areas of the vehicle’s underbody, which eats its way into the vehicle’s base layer over time, causing perforations in several places. It is a sign of degradation that can weaken the frame of your vehicle and jeopardize passenger and driver safety if not controlled and managed. Thus, corrosion prevention is crucial in keeping your investment safe.


Heated Garage is Not the Solution


Many vehicle owners think that their vehicles are well-protected in heated garages. Unfortunately, that is a false theory. Vehicles that are not rust-proofed and kept in heated garages are at a higher risk of corrosion because they can’t defend against humidity or heat in the garage. Heat and humidity activate chemical reactions initiated by exposure to chloride. Needless to say, rust-proofing and undercoating are the best ways to keep your vehicle rust-free and in top condition.


Best Time to Get the Treatment Done


The good news is that it is never too late to get your vehicle rust-proofed. All you have to do is to be proactive. Before winter kicks in, make sure to undercoat and rustproof your vehicle. The best time is summer and spring. These seasons provide a favorable environment—all much needed to maximize the treatment’s effectiveness. In other words, these months are drier, while the roads are not covered with tons of rock salt or continuously wet. Therefore, getting your vehicle rust-proofed in summer or spring will prolong the treatment effectiveness and offer your vehicle a rust protection boost in winters.

To get started with rustproofing and undercoating your vehicle, try NH Oil Undercoating. It is the ultimate way to guard your vehicle against rust and prevent it from further spreading if your vehicle is already exposed to rust formation. The unique formulation of NH Oil Undercoating penetrates deep into cracks, spot welds, and folds prone to hold moisture, pushing out oxygen and moisture to eliminate corrosion from occurring or spreading.

When thinking about corrosion prevention, being proactive about corrosion control is the best way to protect your investments.Catastrophic truck rust damage

Once rust forms, it never really stops. That’s why when it comes to your precious vehicle, the best “cure” is preventative treatment. It is easy to forget that every road without ice this winter is likely covered in salts and chemicals that can be harmful to your vehicle. By being proactive in preventing rust damage in the winter, you can not only avoid unwelcome surprises in the spring but also help maintain your car or truck’s value for years to come.

You may be thinking, well, that’s easier said than done. The best solution is to use a preventative NH Oil Undercoating® to protect your vehicle from rust in the first place. But if you’re experiencing rust already, don’t fret—NH Oil Undercoating® will prevent further spread.


How does NH Oil Undercoating® Work?


NH Oil Undercoating® is a unique blend of highly refined petroleum, 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. It will continue to penetrate to the good metal, pushing out existing moisture and oxygen thus eliminating oxidation-corrosion.


Stop Electrolysis


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 is rusted.


Creeps and Self Healing


NH Oil Undercoating® is designed to creep deep into cracks, crevices, spot welds, seams, 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 makes sure the 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 improves the appearance of any metal surface!
