Underbody Coating
Underbody Coating:
In Indian road conditions, a cars underbody is most prone to corrosion because this area usually comes in contact with water during. Underbody coatitng is highly recomanded with the places which observe high rainfall. 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. Underbody coating can also reduce wear and tear.

Underbody coating is generally a dense cladding (usually based on rubber) applied uniformly to the undercarriage of the automobile. It is normally sprayed or painted on when the car is just out of the dealership and is clean. But even if you are getting the undercoating applied after a couple of years, it’s fine too. This is because it can prevent further damage to the undercarriage.
Please refer to below attaced photo,where you can easily differentiate between coated and uncoated part of underboady.

Types of Undercoating:
- Rubberized Underbody Coating: This is generally thought of as the best underbody coating for your car. It preserves the underbody well, protecting it from scratches. Applying this to the undercarriage is not much of a hassle either.
- Wax Based Underbody Coating: This – more or less – ephemeral undercoating will wear away in a few months’ time. On the upside, wax-based undercoating puts up a big fight against moisture. It is also the most affordable option out there.
- Asphalt Based Automotive Undercoating: Best suited for lorries, trucks and large vehicles this provides a greater degree of protection compared to rubber-based coatings. However, asphalt-based coatings contain little amounts of rubber for sound-insulation purposes. The process of applying this coating is a bit time-consuming though.
- Polyurethane Underbody Coating: This coating closes up splits and fractures on the underbody of the vehicle. It offers up good protection against corrosion and also bonds with the metal. Unlike in the case of asphalt-based coating, you can paint over the polyurethane coating.
Pros of Undercoating:
- 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.
- Prolong Car’s Life: Good undercoating not only defends the underbody from corrosion but also protects the engine and transmission as well! Less rusting coupled with slower wear and tear can surely add years to the lifespan of your vehicle. There would be fewer dents, dings and scratches on the undercarriage for you to fret about.
Cons of Undercoating:
- A used vehicle may already have residue on the bottom of the car or even have spots of rust and corrosion. Undercoating will not help you if corrosion already exists and the corrosion needs to be removed first before it can be applied, which can be expensive for you.
