Rust Can’t Form, Spread or Survive
Our exclusive, eco-friendly, food-grade mineral oil formula forms a flexible, self-healing barrier against salt, dirt and moisture. Unlike traditional coatings that trap rust, NHOU® Oil Undercoating penetrates it, displacing moisture and cutting off oxygen.
The result keeps your vehicle safer and longer-lasting, and helps preserve its value.
I’ve used many types of undercoating on my vehicles since I was 30 years old. Now I’m 75 and had my vehicle undercoated last year with NHOU Oil Undercoating and I’m so impressed. I would highly recommend this product to everyone I know.Paul LaflammeNHOU Customer

Advanced Protection from Salt-Brine Corrosion
Modern vehicles are built with thousands of welds, seams and folds that compromise factory coatings, allowing rust to start before the first mile. Today’s salt-brine solutions, packed with magnesium and calcium chloride, cling to surfaces and penetrate deep into body cavities. Unlike old rock salt, they reach areas never touched before.
NHOU® Oil Undercoating stops this corrosive intrusion, shielding your entire undercarriage from lasting damage.
Fight Rust. Drive with Confidence.
NHOU® Oil Undercoating in Black doesn’t just protect, it instantly enhances the look of any metal surface. Unlike paint or traditional coatings that trap rust, our oil penetrates to the base metal, displaces moisture and blocks oxygen.
This self-healing formula stops oxidation at the source while leaving a clean, black finish.
