How Oil-Based Rustproofing Works

NH Oil Undercoating is a unique blend highly refined Mineral Oil, & Green Corrosion Inhibitors that guard against rust and corrosion on all metals. It eliminates moisture and oxygen while providing a barrier against salt, dirt and other pollutants from the metal providing long lasting protection for your vehicle. 

 

​

Penetrate & Lubricate

After NH Oil Undercoating® is applied, you can expect it to lift and remove dirt, moisture, other contaminants, and even some surface rust. It is designed to penetrate to the good metal and form its protection there. It will continue to penetrate to the good metal, pushing out existing moisture and oxygen, thus eliminating oxidation-corrosion.

 

​

Stop Electrolysis

NH Oil Undercoating® stops electrolysis by disallowing the external circuit to be completed. NH Oil Undercoating is designed as a non-conductive material that also has a voltage drop of only 1/100th of a volt. After securing the connections, it can be used on electrical connections to prevent the “greening” of wires.

 

​

Active Molecular Protective Film

Once NH Oil Undercoating® has reached the good metal, it sets up a bond. This bond is at a molecular level and the film that is created is ultra-thin providing long-term protection. The inhibitors, meshed in a chain link, are then used by the environment – contaminants, salts, etc.… – before the metal is rusted.

​

 

Creeps and Self-Healing

NH Oil Undercoating® is designed to creep deep into cracks, crevices, spot welds, seams, folds and provide protection there as these areas up prone to hold moisture and are unprotected. So even if the initial application cannot reach one of these areas, this creeping process makes sure the maximum protection is provided!

Can we improve the appearance if there’s existing rust?

Yes. NH oil undercoating® Back N Black not only protects but it improves the appearance of any metal surface!
