How Oil-Based Rustproofing works




Unlike paint or conventional undercoating, which cover and encapsulate 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 seems, 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 vehicles body cavities were 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 carwashes 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 vehicles undercarriage where it was never intended to be, can be very counterproductive.

NH Oil Undercoating ® Will provide you superior protection. It remains soft, it 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. Here is how it works .How to Video
