NHOU® Enviro

Introducing the Most Environmentally Responsible Undercoating
After years of development, laboratory testing, and real-world testing at our flagship location in Chichester, New Hampshire, NHOU® is proud to offer our most eco-sensitive, best-performing undercoating ever formulated— NHOU®-ENVIRO™. Bio-based and entirely biodegradable (confirmed by CEC-L-33-T-82 testing), it showed no acute toxicity or adverse effects in aquatic/marine and agricultural applications. The formulation meets or exceeds all regulatory requirements imposed on state and town municipalities—uncompromised Performance.

NHOU®-ENVIRO™ provides superior resistance to water washout and will stay in place longer than other undercoating products.
Its rust-preventing characteristics (corrosion inhibitors) perform equally to our #1 oil undercoating formulation. Misting, creeping, and adhesion are uncompromised, ensuring the best coverage—including inside vehicle frames where rust begins.
