Underbody Coating

• under body coating provides long term protection from corrision to car's under body.
• its also protects part like internal body pannel, frame rails and other inner cavities that are not physically accessible but are prone to corrosion.
• Underboady coatong is usually a dense cladding (often based on rubber ) applied uniformly to the under carriage of the automobile.
• It normally sprayed or painted on when the car is just out of the dealership and is clean.

now let us look at the various kind of automotive underbody coating are exsting in the market

1.RUBBERIZED UNDERBODY COATING

This is generally thought of as the best underbody coating of your car. its preserves the underbody well,protection from scratches.Applying this to the undercarriage is not much of a hassle either.

2.WAX BASED UNDERBODY COATING

This more or less ephemeral undercoating will wear away in few months' time. on the upside, wax-based underbody coating puts up a big fight againt moisture. it is the most affordable option out there.

3.ASPHALT BASED AUTOMOTIVE UNDERBODYCOATING

Best suitable for lorries, trucks and large vechiles this provides a grater degree of protection compared to rubber based coating.

This process of applying this coating is a bit time-cosuming though.

4.POLYURETHANE UNDERBODY COATING

This coating closes up splits and fractures on the underbody of the vechile. It offres up good protrction againt corrosion and also bond with the metal. unlike in the case of asphalt- based caoting ,you can paint over the polyurthane coating.

PROCESS:

• When it comes to updating your vehicle or using any sort of coating, remove the rust completely first and then proceed. Rust removal is easily achieved by sandblasting or sanding, depending on the area and the extent of the rust.

• Once you've removed the rust and prepped your undercarriage for coating, give it a quick rinse and let it dry to ensure you aren't further trapping any contaminants on your vehicle's underbelly. Using a degreaser to clean the metal first is also recommended.

• Most undercoating is generally applied with a spray gun. A disposable spray gun will work best; once the undercoating hardens, it becomes very difficult to clean the gun even with a lot of thinner. A Schutz disposable spray gun is the best option.

• No matter what type of vehicle undercoating you've selected, two coats will provide the optimum protection. Allow ample dry time between coats.

  • Let the undercoating cure completely (usually overnight) before driving your vehicle on the road.pros:

• fight rust
• Absorb noise
• Reinforecement
• prolong's car life
• minimize sound

cons:-

• Apllying underbody coating will not have any effect to the already corroded part.

• Undercoating is costly.

• Since the corrosion itself starts after few year, underbody coating is not preferable to ower who change their car after few year.
