Underbody Coating

UNDERBODY COATING

Definition of underbody coating:

Underbody coating provides long-term protection from corrosion to the 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.

Purpose of underbody coating:

• The main reason for getting an underbody coating is to prevent rusting and corrosion.
• Underbody coating is usually a dense cladding (often based on rubber) 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 underbody coating applied after a couple of years, it's fine too. This is because it can prevent further damage to the undercarriage.
• 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 coatings also reduce wear and tear. Getting a fresh coat can cost you up to 6000 rupees
• This is not only required during the monsoon season but also in hot and humid climatic conditions.
• Reduced the NVH(Noise Vibration Harshness) level.
• Car underbody coating prevents the paint from chipping
• when your car travel at high speed on a highway, thr small stones, and debris hits your car's underbody in this process and may lead to chipping of the underbody paint. hence it is advisable to have a thick layer of under-body coating to prevent paint from chipping.

Process of underbody coating:

• As always when it comes to updating your vehicle or using any sort of coating, remove the rust completely, FIRST, and then proceed. Rust removal is easily achieved by sandblasting or sanding, depending on the area and the extent of the rust.
• Once you've removed the rust and prepped your undercarriage for coating, give it a quick rinse and let it dry to ensure you aren't further trapping any contaminants on your vehicle's underbelly. Using a degreaser to clean the metal first is also recommended.
• Most undercoating is generally applied with a spray gun. A disposable spray gun will work best; once the undercoating hardens, it becomes very difficult to clean the gun even with a lot of thinners. A Schutz disposable spray gun is the best option.
• No matter what type of vehicle undercoating you've selected, two coats will provide the optimum protection. Allow ample dry time between coats.
• Let the undercoating cure completely (usually overnight) before driving your vehicle on the road.

Types of underbody coating:

1. Rubberized underbody coating
2. Wax Based on underbody coating
3. Asphalt underbody coating
4. polyurethane 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. This is widely considered to be the best underbody coating for your car. It protects the underbody from scratches and keeps it properly. It’s also not difficult to apply this to the undercarriage. This can be done at the authorized service center or by the local repair shop at a reasonable price. Rubberized coating is ideal if you want to keep the road noise to a minimum and rust and corrosion away.

WAX BASED ON UNDERBODY COATING:

This more or less ephemeral underbody coating will wear away in a few months' time. On the upside, wax based on underbody coating puts up a big fight against moisture. It is also the most affordable option out there. This transitory undercoating will, on the whole, fade away after a few months. On the plus side, wax-based undercoating is resistant to dampness. It is also the most cost-effective alternative.

ASPHALT UNDERBODY COATING :

Best suited for lorries, trucks, and large vehicles this provides a greater degree of protection compared to rubber-based coating. However, asphalt-based coatings contain little amount of rubber for sound insulation purposes. The process of applying this coating is a bit time-consuming though.

Asphalt Based Undercoating does provide some benefits over Waxed Based Undercoating. They both stick well to most any surfaces and do a great job sealing out moisture, road chemicals, and oxygen. But mainly, Asphalt undercoating has the benefit of being less expensive. They protect anywhere up to 5 years and dry to a Firm to Hard coating.

Asphalt Based Undercoating does require a thicker film thickness meaning you will have to apply more product to the surface to be protected than if you use a Wax Based Undercoating. Additionally, Asphalt based products require more surface preparation because they can actually seal in rust and moisture allowing it to continue to grow. Finally, Asphalt based products continue to dry out over time causing cracks in the coating surface.

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 bond with the metal. Unlike in the case of asphalt-based coating, you can paint over the polyurethane coating.

Advantages of underbody coating:

1. Fight Rust

Its plays an important role in keeping corrosion at bay. Underbody coating can come in handy especially if you live near the sea, where there is too much humidity and rusting is just one of those everyday things you should also seriously consider Underbody coating if you reside in a place where it snows in winter.

2. Absorbs noises

Believe it or not, a very thick Underbody coating can soften the noises that reach the cabin. since the Underbody coating is often made up of rubber it absorbs some of the rachets. the occupants of the car could spare themselves from the road noises at least up to a certain extent.

3. Reinforcements

If your car comes with stock Underbody coating, using another coating on top of it, is not going to hurt. It will offer additional reinforcement, protecting the underbody from water road debris, gravel, and small pebbles. There would also be a lesser chance for the factory coat to flake away.

4. Prolong cars life

Good underbody coating not only defends the underbody from corrosion but also protects the engine and transmission as well. less rusting coupled with slower wear and tear can surely years to the life span of your vehicle. There would be fewer dents, dings, and scratches on the undercoating for you to fret about.

THE 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. Undercoatings give 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's 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. Underbody coating 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.
