Types of Under-body coating process:

Basically there are four-types of under-body coatings.

• Rubberized under-body coating.

• It is also the most cost-effective alternative.

Asphalt based automotive Under body coating:

• Suitable for lorries, trucks, and other heavy vehicles.
• In comparison to rubber-based coatings, this gives a higher level of protection.
• Asphalt-based coatings, on the other hand, incorporate a small quantity of rubber for sound insulation.
• The application of this coating, however, takes some time.

Polyurethane under-body coating:

• This covering seals breaks and fractures in the vehicle’s underbody.
