Underbody Coating:

Underbody Coating is the proces of coating the underneath components of the vehicle such a cars whose components are much prone to get damaged by sand and stones while driving. 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.

The primary objective of getting underbody coating done is preventing metal components that are exposed on the bottom side of the car to damage from corrosion. You can shut out the Adverse effects of corrosion on your car by simply applying a rubberised anti-rust coating all over the bottom-side of your car.

Types of UnderBody coating:

There are presently 4 types of undercoating which are as follows.

Rubberized Under Coating:

Asphalt Based Undercoating:

Asphalt-based undercoating generally contains a little bit of rubberized material that sets up firmly and also helps soften noise. Generally sold in five gallon containers, this type of undercoating also needs more cure time than the other three, and is NOT paintable, making it best to use only for undercarriages.
