The Official Oil-Based Rust Prevention System

It’s not just an undercoating. It’s a commitment…

Most people will never see the underside of your car, but that doesn’t mean it shouldn’t look good too. Besides looking good, it’s important your car’s chassis and undercarriage are well protected from the elements. The sand, salt and moisture the underside of your car has to deal with is much harsher than what the shiny side gets. The destructive force of corrosion is the single greatest threat to your vehicle. It can lead to rapid deterioration of metal, not only resulting in poor appearance and loss of value, but hazardous safety issues as well. Don’t wait until you have a structural failure, or fail a safety inspection. Deal with rust as you would any other maintenance item on the vehicle.  Our products deal with the less than perfect foundations you sometimes have to start with down there. NH Oil Undercoating® can keep them looking that way for a long time. Our environmentally friendly oils will displace moisture and cut off the oxygen supply to existing rust.

 More cars are destroyed each year by rust than by auto accidents, according to the Automobile Association of America!  Save your vehicle today!

When it comes to rust and corrosion prevention… We’ve got you covered!

Despite recent advances in the materials and manufacture of vehicles, corrosion is still with us. You can hardly miss the effects of rust. Fortunately, rust/corrosion prevention is still possible. By following a regular program of  NHOU® Oil-based rustproofing corrosion prevention coating, you can keep your car in excellent condition. Here’s how video 

NH Oil Undercoating® your car or truck is one of the best ways to stop corrosion before it starts. Applying NHOU automotive undercoating to a vehicle puts a physical barrier between the exposed underbody and all the road brine just waiting to pummel it. The chemical make-up of brine has industry experts warning drivers of its corrosive nature. “The solution, once it gets into crevices of a vehicle, is highly corrosive,” said Bob Baboian, an auto industry consultant and fellow with the National Association of Corrosive Engineers. “Brine is highly effective, but can cause serious damage to vehicles if it’s not immediately addressed.”

By the time the corrosion becomes visible, its effects may already be widespread. 

All our products offer powerful corrosion protection for all metals . They are long lasting, and made of the highest quality corrosion preventives and lubricants available on the market.

                                  Minimize corrosion damage and maximize protection for your investment!

What is a “high salt” diet costing you?

NH Oil Undercoating will protect your vehicle against damage caused by salt, liquid de-icing  trapped in your body cavities, cracks and crevices and spot welds over the winter. It’s designed to penetrate the seams and crevices. It eliminates moisture and oxygen on all metals, it protects  and improves the function of moving parts through lubrication.

Spring temperature changes from cold to hot… freezing and thawing is devastating to the seams and spot welds of a vehicle. Trapped moisture freezes and the expansion of the crevice ruptures the paint and creates a cavity that only needs the warm sun to cook the rot. Rust and corrosion undermine the structural integrity and negatively affect the overall appearance of your vehicle and reduce the value and life of the vehicle.
