NHOU Oil Undercoating is a modern product engineered exclusively for preventing rust on vehicles—constantly being improved to perform better and last longer.

Other undercoatings rely on centuries-old recipes, some of which were never intended to be undercoatings—like Cosmoline invented in the mid-1800s to promote hair growth.

NHOU Oil Undercoating mists and creeps into all the little places rust begins—with a dime-size drop creeping more than 7 inches.

Other undercoatings neither mist or creep, meaning they have no way of getting deep into body cavities or frames—or even worse, they trap moisture against the metal and speed up the rusting process (like paint-based products).

NHOU Oil Undercoating is applied with custom equipment, manufactured just for NHOU by the leading global supplier—it lets us get the oil into every single part.

Other undercoatings are applied with generic, off-the-shelf equipment that isn’t designed to access every part of the frame and body cavities.

NHOU Oil Undercoating is infused with Mouse-Out, a proprietary formulation that repels rodents four ways: touch, taste, scent and predatory fear (scent undetectable by humans)—rated 92% effective in third-party laboratory testing.

Other undercoatings don’t repel mice, leaving your vehicle’s wiring susceptible to rodent damage including chewed wires, which mice are attracted to because of soy-based coatings.
