NHOU® Oil Undercoating
NHOU® Oil Undercoating is our flagship product, trusted by tens of thousands of satisfied customers across the globe. This exclusive, eco-friendly formulation creates a protective barrier against salt, dirt, and other pollutants, offering long-lasting protection to all metal parts on 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.
The blend of highly refined mineral oil and green corrosion ingredients guards against rust and corrosion on all metals. NHOU® Oil Undercoating is designed to penetrate the good metal and form its protection there. After reaching the good metal, it sets up a bond at the molecular level to create an ultra-thin, long-term barrier of protection—guarding against road salt brine and environmental damage.
