Underbody Coating
Under-Body Coating gives protection for long term to car's underbody from corrosion.
It also provides protection to parts like internal body pannels, frame rails and other inner cavities that are not physically accessible but are prone to corrosion.
It is normally sprayed or painted on when the car is just out of the dealership and is clean. But it’s also okay if undercoating is done after a couple of years.
Types of Under-Body Coating
1 Rubberized Underbody Coating
2 Wax Based Underbody Coating
3 Asphalt Based Automotive Undercoating
4 Polyurethane Underbody Coating
Rubberized Underbody Coating- This is considered to be the best underbody coating for one vehicle. It protects the underbody from scratches. It’s also not difficult to apply this to the undercarriage. This can be done at the authorized service center or by the local repair shop at a reasonable price. Rubberized coating is ideal if you want to keep the road noise to a minimum and rust and corrosion away.

Wax Based Underbody Coating-
This undercoating fade away after a few months. With addition to protection wax-based undercoating is resistant to dampness. It is also the most cost-effective alternative.
Asphalt Based Automotive Undercoating-
In comparison to rubber-based coatings, this gives a better of protection. Asphalt-based coatings also have a small quantity of rubber for sound insulation. The application of this coating takes some time. It is suitable for lorries, trucks, and other heavy vehicles.

Polyurethane Underbody Coating
This covering seals breaks and fractures in the vehicle’s underbody. It provides strong corrosion resistance and also binds to the metal. Unlike an asphalt-based coating, the polyurethane coating may be painted over.
