How does NH Oil Undercoating® Work?

NH Oil Undercoating is a unique blend highly refined petroleum, rust inhibitors that guard against rust and corrosion on all metals. It eliminates moisture containing 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 together 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, spotwelds, seems, 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 ceeping process makes sure the maximum protection is provided!

Whether your vehicle is brand new or 10 years old, rust proofing using NH Oil Undercoating ® makes perfectly good sense.  Oil rust proofing is done once a year, preferably before the harsh New England winters settle in and wreak havoc on your vehicles undercarriage. Your vehicles paint protects it for the most part, but the undercarriage is left exposed to the elements and that is where rust can take hold. At  NH Oil Undercoating we make sure that your undercarriage is completely protected from the elements using NH Oil Undercoating, a non conductive,  non drying and eco friendly mineral oil that will not drip or freeze.

All our specialized products will protect your vehicle against auto corrosion damage caused by salt, liquid de-icing and winter driving conditions. They are designed to penetrate the seams and crevices. It eliminates moisture. It actually stops rust and corrosion in all metals, (when present) it protects vinyl and plastic surfaces from UV rays and improves the function of moving parts through lubrication.

The fact is, a new vehicle is subjected to thousands of spot welds and numerous bends and folds during production.
This process damages the pre-coated metal, allowing exposure to the corrosion process. Besides cosmetic damage, corrosion also weakens a vehicle’s structural integrity and can affect steering and suspension components.
