This product 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.


Unlike paint or conventional undercoating, which covers and encapsulates rust, our oil penetrates through rust to the base metal. Our oil is self-healing, designed to displace moisture and remove oxygen. Take either out of the equation and oxidation cannot occur. Our corrosion inhibitors will then fight rust on a chemical level. Our oil is formulated to penetrate deep into seams, body cavities, and spot welds, creating a barrier against the elements in an environment prone to hold moisture and conducive for corrosion.


With the introduction to road brine ( liquefied salt ) this extremely corrosive solution is now able to penetrate deep into your vehicle’s body cavities where rock salt could not. Many of these road brine solutions contain magnesium chloride, calcium chloride, and additives to help them stick to surfaces.


Problem is, they don’t discriminate. For most people, a car wash is their maintenance program. Unfortunately, this can prove detrimental to combating corrosion. Many car washes recycle water, likely not eliminating all of the corrosive solutions. Combine that with the fact that it’s pushing with high-pressure water into your vehicle’s undercarriage where it was never intended to be, which can be very counterproductive.


NH Oil Undercoating Will provide you superior protection. It remains soft, compensates for heat and will not dry or crack like traditional hard-coatings, and will substantially reduce the corrosive effects your vehicle is subject to during winter conditions. In our opinion, Oil-based rustproofing is the most forgiving way to treat corrosion.
