Underbody Coating

Under-Body Coating:

Underbody coating is usually a dense cladding applied uniformly to the undercarriage of the automobile.

Purpose

The main purpose of undercoating is to prevent rusting of body components like frame rails along with other metal parts exposed to the environment. Under-body Coating can also reduce wear and tear.

Types

• 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 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 Undercoating

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.

Pros

• Fights Rust
• Absorbs Noise
• Reinforcement
• Prolong Car’s Life

Cons

• It is less helpful if corrosion is already present.
• It works best on new cars.
• Most vehicles make it five years before corrosion begins to show.
• It adds weight to the vehicle and adds cost.
