Annual oil undercoating built for northern winters and road brine, applied by an authorized NHOU applicator.
Unlike traditional rubberized or hard paint undercoatings that trap moisture and accelerate hidden rust, NHOU® is an actively creeping petroleum- and oil-based rustproofing treatment.
It displaces moisture, deprives surface metal of oxygen, and creeps into hidden frame channels, rocker panels, and seams where rust starts.
A highly refined petroleum-oil-based formula tinted with biodegradable carbon graphite. It penetrates surface rust, remains active, and restores a clean, dark OEM look to the undercarriage.
Combines petroleum-based oils, wax, and lanolin. V3 creates a thicker, longer-lasting barrier against salt spray and gravel abrasion while keeping deep penetration and self-healing properties.
NHOU® is non-corrosive and safe for electrical wiring and sensors.
NHOU® products are engineered not to drip. Slight dripping can happen in rare cases in tight crevices or warm weather, and cleans up with common soaps like Dawn or Simple Green.
Drive and wash as usual. Skip high-pressure hot-water undercarriage sprays at automatic car washes, which can strip protective oil layers over time.
We recommend an annual application or touch-up for maximum protection against harsh New England road salt and liquid de-icers. Book in the fall, before the first salt hits the roads.
See the official NHOU® FAQ for chemical breakdowns, testing data and product details.
Our body shop handles the rust that's already there, then we protect it so it doesn't come back.
