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.

NHOU is the only undercoating brand with its own shop that services thousands of vehicles every year. That means our experts are able to see how every NHOU formula performs over the years. With our own in-house lab and chemists working to improve every product as the science progresses, NHOU is always at the forefront of rust protection

Unlike paint or conventional undercoating, which encapsulates rust and traps moisture, NHOU undercoating formulas are mineral-oil-based to penetrate through rust to the base metal. Our formulas are engineered to be self-healing as they displace moisture and remove oxygen—eliminating the possibility of rust. Our undercoating products are formulated to penetrate deep into seams, body cavities and spot welds, creating a barrier against the elements.
