Underbody Coating

Underbody Coating

In Indian road conditions, a cars underbody is most prone to corrosion. It plays a very important role in the service life of the vehicle. Under body coatings are done to protect the vehicle chassis from external environment there by ensuring the integrity and safety of cars. Underbody coating provides long term protection from corrosion to car’s underbody. It also protects parts like internal body panels, frame rails and other inner cavities that are not physically accessible but are prone to corrosion.

Some of the factors that make Underbody Anti-Rust Coating :-

• Protects Against Rust & Corrosion

Environmntal factors like heat,moisture, atmospheric salts will affect the under body of a car. Particular in coastal areas, the wind from the sea will bring more salt to the air, which will accelerate the corrosion and reduce the service life of a car. When the under body is covered with thick and tight layers, it would act as a strong barrior to prevent these external substances affecting the metal sheet.

• Noise Vibrations Harshness( NVH) Levels Reduces

Our country is filled with roads having uneven patches and potholes and while we manoeuvre our cars through such sections, the unpaved crumbs, and pebbles hit the car from underneath or get stuck in the wheel wells. The underbody coating’s consistency is so thick that the layer it creates absorbs all the unpleasant noises and vibrations and marginally improves the driving experience.

• Prevents Paint Chipping
• Road debris constantly hit your car under body while driving. In some cases, the under body might be scratched by uneven road damaging the protective coating on the metal sheet and leaving the bare metal exposed to the air, which results in corrosion when in contact with the moisture in the air. If not promptly getting anti-rust treatment, then the rust will soon spread to large areas. Under body coating is a thick elastic layer which could not be easily damaged by stone chipping or scratch, therefore could basically protect the metal sheet of the under body
• Protects Vital Components

Underneath a car is somewhere a lot of indispensable parts of a car are left exposed like the Engine, silencer, etc. One simply can’t afford to let these parts go bad due to rusting and hence in order to save yourself from a hefty repair bill, a considerably less expensive Anti-Rust Coating is a must.

Types of Underbody coating

Now let us look at the various kinds of automotive underbody coating you can go for, for your vehicle.

1. 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.

2. 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.

3. 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.

4. 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.

Pros of Undercoating

The obvious pros of undercoating are the protection it provides to the carriage of your vehicle. If you live in an area where salt and sand are used on the roadways in cold weather, these materials can be corrosive to your vehicle. Undercoating gives you an extra layer of protection against rust and corrosion, protecting your car. Undercoating will eventually wear out, but you can get years of protection from it. Even vehicles in warmer climates gain protection as debris is repelled and kept away from eating at the vehicle.

Cons of Undercoating

When examining the vehicle undercoating pros and cons, you do want to look at potential downsides to getting undercoating. Undercoating will work best on new vehicles that have not been exposed to road conditions. A used vehicle may already have residue on the bottom of the car or even have spots of rust and corrosion. Undercoating will not help you if corrosion already exists and the corrosion needs to be removed first before it can be applied, which can be expensive for you.
