Every NHOU undercoating formula is engineered to creep into all the little places rust begins—sealing out corrosives and eliminating rust. Today’s vehicles are made with thousands of folds, spotwelds and seams, all of which are susceptible to rust and corrosion. To make vehicles more fuel efficient, manufacturers use thinner and lighter metals that corrode faster than those made ten years ago. At the same time, ice-melting road-salt brines now have adhesive ingredients that cause them to stick to car frames. NHOU Mil-Spec formulas are laboratory-engineered and real-world proven to force out moisture and seal off oxygen—making rust impossible.

We’ve seen some pretty dramatic transformations in our years of applying NH Oil Undercoating®!








Founder Joe Dupont works with a laboratory to engineer every NHOU® product—ensuring it protects and lasts. NHOU® has grown from a part-time operation out of a family garage, to becoming a leading, globally recognized brand.
NHOU is always making our products better, constantly tweaking each formulation as the science progresses and evolves. With over 15,000 oil coatings under our belt, we’ve expanded to include Rustorations®, wax/oils, protecting your vehicle from top to bottom!
Absolutely not! Because NH Oil Undercoating® is an entirely different approach, it eliminates annoying electrical malfunctions and makes the vehicle work better and last longer. While the manufacturers probably won’t admit it, they just have to love NH Oil Undercoating® because it will reduce the number of corrosion related warranty claims they are obligated to pay. It also saves customers the time and aggravation associated with claims against warranties. NH Oil Undercoating is used and sold by most major manufacturers dealerships.
NHOU is atomized under high pressure which pushes the product deep into the seams, cracks and crevices where corrosion starts. Once applied, the product removes the moisture in these areas and provides a strong adherence to these surfaces, remaining active with excellent “creeping” and self-healing abilities.
