Underbody Coating

Under-Body Coating

A car’s underbody is exposed to the most wear and tear caused by muddy water, potholed roads, stones and other obstacles on the road. Because it’s not in plain sight, we often do not see the damage. So it is neccessory to protect the under-body of a vehicle.

Underbody coating is usually a dense cladding 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. But even if you are getting the undercoating applied after a couple of years, it’s fine too. This is because it can prevent further damage to the undercarriage.

Also, 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. It also protects parts like internal body panels, frame rails and other inner cavities that are not physically accessible but are prone to corrosion.

There are 4 types of under-body coating available.

1. Rubberized Underbody coating
2. Wax Based Underbody coating
3. Asphalt Based Automotive Undercoating
4. Polyurethene 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.

Polyurethene 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.

Advantages

• Fights against rust and protect the underbody
• It absorbes noise
• It provide reinforcement to the car
• It increases the car's life span

Disadvantages

• It will not help you if corrosion already exists
• It is not suitable for old vehicles
• Expensive
