Underbody Coating

1. What is Under body Coating?

Underbody coatings are those which are used to prevent car bodies against rust & corrosion. This underbody coating helps in protection from dust and moisture also some other factors such as poor road conditions, rocks getting thrown from tires and denting the metal and salt from water during monsoon which plays an important role in damaging the underbelly of a car.

Types of Undercoating

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.

Advantages of Undercoating

• 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.

• Warranty and Other Perks
  
  You can get a warranty on many undercoatings.Underbody coatings can also make it easier for you to clean the car. Besides these, the coating provides a bit of thermal insulation making travelling by road easier even during summers.

Pro's:

1. It provides a layer of protection against corrosion.

2. It will extend the life of your vehicle.

3. It can be applied to damaged areas.

4. It may help to reduce interior noise.

Con's:

1. It is less helpful if corrosion is already present.

2. It works best on new cars.

3. Most vehicles make it five years before corrosion begins to show.

4. It adds weight to the vehicle.

5. An undercoating is not impervious to damage.
