NHOU Oil Undercoating

ANNUAL RUST PROTECTION FOR ALL VEHICLES

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. Pleasant smell.

Warranty 18 months on the bottom 36 months warranty on hidden cavities

Not aggressive to rubber and plastic

It does not drip, and leaves no dirt

Processing from 2 hours

How Oil-Based Rustproofing works

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, 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 ceeping 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!

Rust protection on the chemical level

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.

Car processing steps

  • Preparatory phase (preliminary car diagnostics, underbody cleaning, drying)
  • Identification of problem areas and development of an individual protection complex
  • Processing of hidden cavities of the lower part — the base of the body (side members, sills, welds, hollow suspension brackets, transverse beams)
  • Processing underbody, wheel arches (covering underbody, wheel arches, frames ..)
  • Processing of hidden cavities of the upper part of the body (doors, wings, arches, hood cover, trunk lid, engine compartment, contact group).
  • Final stage (coating control, final body wash)

FAQ

NH Oil Undercoating® is a highly refined food-grade mineral oil product. Formulated with the environment in mind, NH Oil Undercoating is a nonhazardous unregulated product. It causes no health or flammability hazards.

The technical term is resolute oil, otherwise known as mineral oil. It is a food-safe grade oil, which means you can consume it in small quantities. Of course I’m not encouraging you to try. However, we had a customer call last year whose pet dog did just that. The only adverse reaction was loose stool! No solvents and no detergents. Corrosion inhibitors are all green and environmentally friendly.

Our oil has natural corrosion inhibitors otherwise known as «green inhibitors», derived from plants and animal fats. Contains no solvents or detergents. It is an environmentally friendly product considering it does not drip. (Minimal dripping may occur). Our NH Back-N-Black has a biodegradable tint, otherwise the same as the clear product.

In our opinion, Oil-based rustproofing is the most forgiving way to treat corrosion.

Our oil is formulated to displace moisture, the presence of oil will deprive the surface of oxygen. When you take either out of the equation, oxidation cannot occur, so as long as the product is present rust is held at bay. NH Oil will simultaneously fight corrosion on a chemical level as well. The presence of the oil will form a barrier to protect the surface. NHOU Is formulated to migrate and creep. 

This is especially important to the weak areas of a vehicle, rocker panels, door panels, etc. areas that are by design prone to rust. The surfaces are generally unprotected with a finish (paint), prone to hold moisture and are very thin. Over the course of a warm month, it is not uncommon for our oil to move as much as several inches. In a cross member of a pickup truck bed, that would encapsulate the entire inside surface area. Having some surface rust can actually be a plus. Much like using an abrasive to scuff a surface prior to applying a finish, the rust will give the product something to hang on to.

Absolutely not! Because NH Oil Undercoating® is an entirely different approach, it eliminates annoying electrical malfunctions and makes the vehicle work better and last longer. While the manufacturers probably won’t admit it, they just have to love NH Oil Undercoating® because it will reduce the number of corrosion related warranty claims they are obligated to pay. It also saves customers the time and aggravation associated with claims against warranties. NH Oil Undercoating is used and sold by most major manufacturers dealerships.
NH Oil Undercoating is formulated not to drip. However, minimal dripping may occur if the product is applied heavily. In most cases clean up is simple, Dawn dish soap or Simple Green usually does the trick.
Check with your dealer, each shop is independently owned and operated. In most cases, if your vehicle arrives with a heavy residue of mud, flaky rust it would be necessary to wash/remove before treatment. We recommend that any heavy accumulation of mud and dirt be pressure washed from the frame and wheel wells a day prior to the application.

Note, arrangements may be necessary to allow adequate time for preparation and additional costs may occur.

Of course it can. Because OIL chases water, it can be applied on rainy days. Water actually accelerates the creeping abilities because it moves quickly on wet surfaces to attack and displace moisture in tight seams and hard to reach crevices.

Some competitor’s products are designed to mix with water with the idea that when the product drips off, the water goes with it. Not so with our products. We make sure that our chemical chases only the water from the metal. This is another reason why our products give longer lasting protection to your vehicle.

You can wash your vehicle immediately after the treatment. But you should avoid high-pressure undercarriage washing. Unlike other preventing methods, it will not trap moisture. It literally pushes it away, leaving behind a corrosion-fighting lubricating film.

NHOU is atomized under high pressure which pushes the product deep into the seams, cracks and crevices where corrosion starts. Once applied, the product removes the moisture in these areas and provides a strong adherence to these surfaces, remaining active with excellent «creeping» and self-healing abilities.
You may notice smoke and odor from the underside of the vehicle the first time the vehicle is driven. This is due to a small amount of overspray vaporizing on the exhaust system. It is harmless and should cease quickly.
You may notice a grinding noise when braking. This is due to a small amount of over-spray collecting on the brake lining. This is not a safety hazard and should cease after a few stops. Paint: NHOU’s products cannot stop scratches, peeling of paint or stone chips. Damage to exterior paint should be repaired promptly otherwise surface corrosion can occur.
While driving habits may vary, we recommend an annual application in order to maintain adequate protection.
The bulk flash point of NH Oil Undercoating® NAS is 218.33°C.
No. NHOU is non-conductive and will not harm electrical connections. Make sure that all connections are made before applying NHOU.
