Underbody Coating

Underbody Coating is usually a dense cladding applied uniformaly to the undercarriage of the automobile. It is normally sprayed or painted on when the car is just out of the dealership & is clean. But even if you are getting the undercoating applied after ta couple of years, it's fine too. This is beacause it can prevent further damage to the undercarriage.

Automotive underbody coatings are applied on the underside of vehicles to provide a protective layer of protection b/w vehicles underside & damaging forces such as moisture, corrosion, stone chip damage & weather resistance.

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

Difference B/w the Rust Protection & Underbody Coating

Underbody Coating & Rust Protection often go hand-in-hand, but they are actually two different things. Rust Protection generally goes inside your vehicle, while Underbody coating is used for protection outside of the vehicle & there are varitiey of Coatings available.

Benefits of Underbody Coating

Underbody Coating gives you an extra layer of Protection against rust & corrosion. Protecting your car Undercoating will eventually wear out, but we can get years of protection from it. Even Vehicles in warmer climats gain protection as debris is repelled & kept away from eating at the vehicle.

TYPES OF UNDERBODY 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.
