Underbody Coating
Under Coating:
Underbody coating means a coating labelled and formulated for application to wheel wells, the inside of door panels or fenders, the underside of a trunk or hood, or the underside of the motor vehicle.
Underbody coating must be checked for peeling&spalling, If wear exists, coating1 must be renewed in required areas.
TYPES OF COATING:
- 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:
- Fights Rusts
- Absorbs Noise
- Reinforcement
- Prolong Car’s Life
- Warranty
CONS:
- Adds extra weight
- undercoating is not impervious to damage
- Has to be reapplied regularly
- Not helpful if corrosion already exists
