Underbody Coating

UNDERBODY COATING Car

undercoating, in a nutshell, is a type of defensive layer that’s applied to the undercarriage of vehicles. A car’s underbody is exposed to the most wear and tear caused by muddy water, potholed roads, stones and other obstacles on the road. In Indian road conditions, a cars underbody is most prone to corrosion. Underbody coating provides long term protection from corrosion to car’s underbody. It also protects parts like internal body panels, frame rails and other inner cavities that are not physically accessible but are prone to corrosion.

1. Water- and Paraffin-Based Undercoats Water-based undercoatings are the most popular for do-it-yourselves. These undercoatings can be found in automotive parts stores in aerosol formats. Water-based undercoatings are thin set and have quick drying times. This type of coating can be done by automotive shops that offer undercoating services inexpensively.

2. Petroleum- and Rubber-Based Undercoats Petroleum-based undercoatings are made from oil and have greater deflective abilities for road salts and grime. The petroleum base helps repel water and ice better than paraffin- or water-based undercoatings.

3. Asphalt-Based Undercoats Asphalt-based undercoating is the strongest undercoating available. It is used on all-terrain and military vehicles. Asphalt-based undercoating will last longest and is the best option for vehicles that endure heavy road use. Asphalt-based undercoating is the thickest coating with the most damage-resistant properties.

ADVANTAGES OF UNDERBODY COATING: Minimizes Sound: It minimizes the sound from underneath the car resulting a noiseless, smooth driving experience.

Heat Insulation: It insulates the interior of the car from extreme temperatures from beneath the vehicle providing a comfortable cabin experience.

Anti-chipping property: If any stone hits the coating it does not get chipped away hence protects the underbody from exposure to water.

DISADVANTAGES OF UNDERBODY COATING:

Oil-based Rustproofing must be reapplied every year for the best results.

The only way for an undercoating to provide ongoing protection for your vehicle is to have the service repeated frequently.
