Undercoating your car or truck is one of the best ways to stop corrosion before it starts. Applying NH Oil Undercoating automotive undercoating to a vehicle puts a physical barrier between the exposed underbody and all the road brine just waiting to pummel it. Don’t wait until you have a structural failure or fail a safety inspection. Deal with rust as you would any other maintenance item on the vehicle. Unlike paint or conventional undercoating, which cover and encapsulate rust, our rust prevention methods and products penetrate through rust to the base metal. NH Oil Undercoating Vehicle Undercoating Service is designed to create a barrier that can’t be broken, chipped or cracked. By staying fluid, our petroleum-based rust protection heals back over after any abrasions providing lasting protection, even in extreme conditions.
