Underbody Coating

UNDERBODY COATING:

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.

Benefits

•  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.

TYPES:

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. A resistant protective coat forms once it has dried, which is resistant to weather, road salt and acids.

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.

 

 

Advantages of Undercoating:

Fights Rust

It plays an important role in keeping corrosion at bay. Underbody coating can come in handy especially if you live near the sea, where there is too much humidity, and rusting is just one of those everyday things. You should also seriously consider undercoating if you reside in a place where it snows in winter.

Absorbs Noise

Believe it or not, very thick undercoating can soften the noises that reach the cabin. Since the undercoating is often made up of rubber it absorbs some of the rackets. The occupants of the car could spare themselves of the road noises – at least up to a certain extend.

Reinforcement

If your car comes with stock underbody coating, using another coating on top of it, is not going to hurt. It will offer additional reinforcement, protecting the underbody from water, road debris, gravel and small pebbles. There would also be a lesser chance for the factory coat to flake away.

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.

 Disadvantages of Undercoating:

Regarding this there will be a disadvantage, that is , if the coating is applied over the corroded part or rusted part, that will be the worst in case regarding safety for the under body. As this will not protect the underbody of the car, and it increases the corrosion and rust.

Initially the car coming from manufacturing yard the finsh under the body will be smooth, such that the coating will be like painted smoothly finish,which it doesn't allow to stick the dirt, gravel, debris, and small particles on it.

After driving for kms the coating layer gets off and the surface of the underbody will get rough, if the coating is done over this, the coating will be settled in an rough and unsmoothened manner which lead to stuck the dirt and dust particles. That will be a disadvantage whe n the coating is done like that. 

We can not specify any disadvantage on this undercoating process, as this is mainly the best part for safety for underbody.
