Underbody Coating

UNDERBODY COATING:

Underbody coating means similar process like painting and we can make a process. Underbody coating in cars means to avoid corrosion to frame and provide long term protection. Rust is the main enemy to the car owners, it will damage all our car parts. Underbody coating is doing because it will protect our vehicle bottom from salt, rock, gravel, moisture and other corrosive substance. It can be apply by automatic or manual to the vehicle because it is C-Class area.

BENEFITS OF UNDERBODY COATING:

By applying this underbody coating we can avoid the heat from the bottom side during vehicle running.

It will arrest the noise from the running units below the vehicle.

By this we can avoid accumulate of the unwanted liquid particles because of the smooth surface.

It is a single coating and if we do it will withstand minimum of 3-5 years, so that it will be cost effective.

It can be easily serviceable if it look same as new at the time of surface.

By doing this aesthetic look we can improve.

TYPES OF VEHICLE UNDERBODY COATING:

There are different type of underbody coating and they will use depend upon the company requirement and types are as follows.

Rubberized undercoating is easy to apply, and generally offers the best protective coating for your car’s undercarriage. It cushions surfaces against moisture, rust, dings, and dents. Rubberized undercoating is safe to use on quarter panels and wheel wells and dries with a soft rubbery finish.

2. ASPHALT-BASED UNDERCOATING:

Asphalt-based undercoating offers a higher level of protection suitable for large trucks, recreational vehicles, and heavy machinery. It’s formulated with some bits of rubberized material to aid in noise reduction. It offers extra protection against chips and moisture but is not paintable and, therefore, only suitable for undercarriages.

3. POLYURETHANE UNDERCOATING:

Polyurethane coating is easy to apply and works by sealing up cracks and seams. The compound displaces salt and moisture and protects the unoxidized metal from rust. It’s often sold in canisters that are ready to preload into an application gun. It, however, requires some surface prep work before application, like degreasing, and applying an etching primer to the bare metal.
