Engineered for vehicles with any amount of rust—from brand new to severe corrosion—NHOU® Oil Undercoating is our flagship product, trusted by tens of thousands of satisfied customers across the globe. Our exclusive, eco-friendly (food-grade mineral-oil-based) formulation creates a protective barrier against salt, dirt, and other pollutants, offering long-lasting protection to all metal components of your vehicle’s undercarriage. Unlike paint or traditional undercoatings that simply cover and encase rust potentially making it worse, NHOU® Oil Undercoating penetrates through rust, pushes out moisture, and eliminates oxygen. With NHOU®, rust simply can’t develop—keeping your vehicle safer to drive, more cost-effective to maintain, and preserving its highest resale value.
Exclusive Formulation
Available in Clear and Black, NHOU Oil Undercoating is a blend of highly refined mineral oil and green corrosion ingredients that guard against rust and corrosion on all metals. NHOU® Oil Undercoating is designed to penetrate the good metal and form its protection. After reaching the good metal, it sets up a bond at the molecular level to create an ultra-thin, self-healing, long-term barrier of protection—guarding against road salt brine and environmental damage.

Combatting Corrosive Salt-Brine
Today’s vehicles are manufactured with thousands of spot welds, seams and folds during production. This process damages the pre-coated metal, allowing exposure to the corrosion process before the vehicle is even driven off the lot. Besides cosmetic damage, corrosion also weakens your vehicle’s structural integrity. Modern road salt-brine (liquefied salt) is an extremely corrosive solution that will penetrate deep into your vehicle’s body cavities where old fashioned rock salt could not. Many of these salt-brine solutions contain magnesium chloride, calcium chloride, and additives to help them stick to surfaces. That means they stick to your vehicle’s frame—its exterior and interior—like never before. NHOU Oil Undercoating protects every inch of your vehicle’s undercarriage, preventing road-salt brine from causing irreversible damage.
Can We Improve the Appearance if There’s Existing Rust?
Yes. NHOU Oil Undercoating in Black not only protects but instantly improves the appearance of any metal surface.
Unlike paint or conventional undercoating, which covers and encapsulates rust, our oil penetrates through rust to the base metal. Our oil is self-healing, designed to displace moisture and remove oxygen. Take either out of the equation, and oxidation cannot occur. Our corrosion inhibitors will then fight rust on a chemical level—all while covering rust with a fresh, black finish.
