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 not only protects—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.
