Underbody Coating

UNDERBODY COATING -

Underbody coating is usually dense cladding (often based on rubber) applied uniformly to the undercarriage of the automobile. It is normally sprayed or painted on when the car is just out of the dealership and is clean.

The main purpose of undercoating is to check rust, especially in the body components like frame rails along with other exposed metal parts. Underbody coating can also reduce wear and tear.

On Indian roads, car underbody is prone to rust easily because of the seasonal & humid conditions.

Under Indian road conditions, a car's underbody is most prone to corrosion. Underbody coating provides long-term protection from corrosion to the 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 coming from underneath the car resulting in a noiseless, smooth driving experience.
• Heat insulation: It insulates the interior of the car from extreme temperatures beneath the vehicle, providing a comfortable cabin experience.
• Anti-chipping property: If any stone hits the coating it does not get chipped away, hence protecting the underbody from exposure to water.

1. 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.

2. Wax-based underbody coating –

This – more or less – ephemeral undercoating that 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.

3. Asphalt based underbody coating –

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 small amounts of rubber for sound-insulation purposes. The process of applying this coating is a bit time-consuming though.

4. Polyurethane underbody coating –

The coating closes up splits and fractures on the underbody of the vehicle. It offers 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 OF UNDERBODY COATING –

1. Fight’s rust
2. Absorb Noise
3. Reinforcement
4. Prolonged car life

Cons of underbody coating –

1. It’s less helpful if corrosion was already present.
2. It works best on new cars.
3. A third-party vehicle underbody coating may void the warranty.
4. It adds weight to the vehicle.
5. It’s not impervious to damage.
