Underbody Coating

Aim:

Purpose of Under-Body Coating and its, its types in detail, and its pros and cons.

What is Under-Body Coating?

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.

Types of Under-Body Coating:

1. Rubberized Underbody Coating
2. Wax Based Underbody Coating
3. Asphalt Based Automotive Undercoating
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.

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 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.

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.

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.
