Underbody Coating
UNDERBODY COATING
Underbody Coating is a sprayable coating, which protects the under surface of the vehicle from corrosion.Underbody coating provides long term protection from corrosion to car's underbody. It also protects parts like internal body panels, frame rails .Protecting the underbelly of the car should be our top priority. Especially during monsoon when heavy precipitation causes the roads to become mini-rivers and our cars are left stranded there.
It protects the underbody substrates from:
1. Environmental conditions
2. Dampens sound and vibration
3. Insulates against cold and heat
4. Protects against Corrosion
5. Seals off seams
6. Hides welds, repairs & bodywork with spray
TYPES:
Rubberized Undercoating
Rubberized Undercoating is easy to apply and offers sound-cushioning as well as protection from dust, moisture, and dings or dents.In addition to your undercarriage, rubberized undercoating is also safe to use on wheel wells and quarter panels, and dries to a soft rubbery finish that prevents further rust, damage, or moisture seeps.
Polyurethane Undercoating
The other option for undercoating your vehicle is to use a polyurethane-based sealant. This type of vehicle undercoating is a little bit quicker and easier to apply.This type of sealant works by seeping into all cracks and seams, displacing salt and moisture and oozing around rusty areas to bond with and protect unoxidized metal.
Asphalt-Based Undercoating
For standard vehicles, any of the aforementioned types of undercoating will provide sufficient protection. For large trucks and heavy machinery, asphalt-based undercoating provides a bit of extra durability against rocks, chips, and moisture.

Pros-
-
Minimizes Sound: It minimizes the sound and noiseless, smooth driving experience.
-
Heat Insulation: It insulates the interior of the car from extreme temperatures from beneath the vehicle providing a comfortable cabin experience.
-
Anti-chipping property: If any stone hits the coating it does not get chipped away hence protects the underbody from exposure to water.
Cons-
-
Apllying underbody coating will not have any effect to the already corroded part.
-
It is costly.
-
Since the corrosion itself starts after few year, underbody coating is not preferable to ower who change their car after few year.
