Underbody Coating
Underbody coating is usually a dense cladding (often based on rubber) applied uniformly to the undercarriage of the automobile. It comes in car as a stock or we can just normally get it sprayed or painted on later, when the car is just out for any service.
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.
Types of Undercoating
Now let us look at the various kinds of automotive underbody coating you can go for, for your vehicle.
- 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 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 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.
