You can wash your vehicle immediately after the treatment. (avoid high-pressure undercarriage washing) Unlike other preventing methods, it will not trap moisture. It literally pushes it away, leaving behind a corrosion-fighting lubricating film.
Absolutely not! Because NH Oil Undercoating® is an entirely different approach, it eliminates annoying electrical malfunctions and makes the vehicle work better and last longer. While the manufacturers probably won’t admit it, they just have to love NH Oil Undercoating® because it will reduce the number of corrosion related warranty claims they are obligated to pay. It also saves customers the time and aggravation associated with claims against warranties. NH Oil Undercoating is used and sold by most major manufacturers dealerships.
Check with your dealer, each shop is independently owned and operated. In most cases, if your vehicle arrives with a heavy residue of mud, flaky rust it would be necessary to wash/remove before treatment. We recommend that any heavy accumulation of mud and dirt be pressure washed from the frame and wheel wells a day prior to the application. Note, arrangements may be necessary to allow adequate time for preparation and additional costs may occur.
NHOU is atomized under high pressure which pushes the product deep into the seams, cracks and crevices where corrosion starts. Once applied, the product removes the moisture in these areas and provides a strong adherence to these surfaces, remaining active with excellent “creeping” and self-healing abilities.
While driving habits may vary, we recommend an annual application in order to maintain adequate protection.
