Underbody Coating

                                                                                       UNDERBODY COATING

We all are aware of the fact that the underbody of the previous models was made from durable metals such as steel, which is easily damaged
and oxidized, forming rust

While you are sitting on the driving seat enjoying the smooth ride, the underbody of your car is always exposed to muddy water, stones.
rugged roads, and potholes. This makes it prone to wear and tear, which is often not in plain sight but could lead to serious issues
So, therefore keeping this in mind, underbody coating is required.

A protective coating composition for motor-vehicle underbodies and gravel guards, characterized in that it comprises, in percentages by

In Indian road conditions, a car's underbody is most prone to corrosion. 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.

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 undercoating 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 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. Getting a fresh coat can cost you up to ₹6,000.

The tar-like undercoating acts as a barrier once it hardens, keeping out moisture, salt, and other substances. This undercoating works best when applied to the undercarriage of a new vehicle. It also requires expert application, or it can crack, letting in moisture.

 

Types of underbody coating:

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 amount 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.

    

Advantages of Undercoating

Now we will tell you why you should consider investing in a vehicle underbody coating.

• Fights Rust
  

  It 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 undercoating if you reside in a place where it snows in winter.

• Absorbs Noise

  Believe it or not, very thick undercoating can soften the noises that reach the cabin. Since the undercoating is often made up of rubber it absorbs some of the rackets. The occupants of the car could spare themselves of the road noises – at least up to a certain extend.

• Reinforcement
  

  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.

• Prolong Car’s Life
  

  Good undercoating 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 add years to the lifespan of your vehicle. There would be fewer dents, dings and scratches on the undercarriage for you to fret about.

Disadvantages of Undercoating

Nothing comes for free in this world. The same goes for undercoating.

1. The undercoating or rustproofing spray is heavy in pockets. However, it is nothing when you compare it with the cost of replacing a vehicle after corrosion.

2. 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.

3. Oil-based Rustproofing must be reapplied every year for the best results.
The only way for an undercoating to provide ongoing protection for your vehicle is to have the service repeated frequently. Most owners can have a new layer applied each year without worrying about their underbelly being compromised. In salty or destructive environments this is a must! Don’t wait until you have a structural failure or fail a safety inspection. Deal with rust as you would any other maintenance item on the vehicle.

CONCLUSION

Underbody coating is one of the hidden factors for the prolonged life of the car. As it protects the car from dust, a minor hit of small gravel, minor wear
and tear, and rust. It provides strength to the underbody. But the coating is not for a lifetime, it removes or chipped out as time passes. In the wet area,
the coating damages faster as compared to dry areas. So, therefore, a check-up is required every 1 or 2 years.
