NHOU — New Hampshire Oil Undercoating

Your ultimate rustproofing solution, now available at Carlat.com in Europe.

Why rustproofing matters

Rust is more than a cosmetic nuisance — it's a safety concern that can compromise brake lines and structural components. An estimated 70% of drivers are affected by rust, with millions experiencing rust-related damage. When de-icing chemicals meet metal, corrosion accelerates — the result is costly repairs and a shorter vehicle lifespan. NH Oil Undercoating® (NHOU) prevents this before it starts.

Why rustproofing matters

Introducing NH Oil Undercoating®

NHOU is an advanced, oil-based rustproofing system engineered to protect your vehicle from the inside out. Each formula uses refined food-grade mineral oil combined with eco-friendly corrosion inhibitors, displacing moisture and sealing out oxygen — the two causes of rust.

Self-healing

Formulas continue to coat and protect even after minor scrapes.

Eco-friendly

Free of solvents and harmful chemicals — corrosion inhibitors are derived from plant and animal fats.

Deep-creeping action

Migrates into nooks and crannies over time, especially rocker panels and door seams.

Surface-friendly

Light surface rust actually improves adhesion, giving the formula more texture to grip.

The story behind NHOU

Founder Joe Dupont was frustrated by persistent rust on his truck in New England. Determined not to lose his primary work vehicle, he researched European oil-undercoating techniques and, working with engineers and chemists, developed a specialized, environmentally friendly formula that outperformed generic products. Today NH Oil Undercoating® is trusted by thousands of drivers.
