Underbody Coating
AIM:To make report on under-body coating and its purpose,its type in details,and its pros and cons
THEORY:
What is under-body coating ?
Underbody caoting is a thick resilient coating applied to the underbody or chassis of an automobile to protect against impact damage from small stones, which would rapidly chip ordinary paint, allowing rusting to begin.
PURPOSE:
- Underbody coating provides long term protection from corrosion to 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.
- A car’s underbody is exposed to the most wear and tear caused by muddy water, potholed roads, stones and other obstacles on the road. Because it’s not in plain sight, we often do not see the damage.
- 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 protective coating is used to protect the vehicle chassis from external environment, to ensure the integrity and safety of the car.
- The use of underbody coating plays a very important role in the service life of the vehicle. In general, it is required to spray such a protective coating in the manufacturing of the new car.

TYPES OF 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.

2.WAXED 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 UNDERBODY COATING:
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 UNDERBODY COATING:
- IT EXTENT THE LIFE SPAN OF THE CAR.
- THERES NO ROAD NOICES.
- PREVENT PAINT CHIPPING.
- PROTECT FROM RUST AND CORROSIONS.
- PROTECT FROM EXTERNAL EFFECTS SUCH AS RAIN,SALTY WATER.
- KEEPING THE CAR GLOSY UNDER IT TOO
DISADVANTAGE :
- UNDERBODY CAN OLY APPLIED TO NEW VEHIVLES
- IT IS NOT WORTHIT IF CORROSION IS ALREADY PRESENT
- IT SHOULD BE APPLIED AFTER 2 TO 3 YEARS FOR BETTER PERFORMANCE
- IT INCREASES THE WEIGHT OF THE VEHICLE
CONCLUSION:
UNDER-BODY COATING IS COMPULSORY TO PROTECT YOUR VEHICLES FROM GETTING RUST AND CORRODED AND KEEP IT MAINTAIN AND NEW AFTER YEARS BY GIVING A EXTRA LAYER OF PROTECTION UNDER NEETH THE CAR ESPECCIALY FOR INDAIN ROADS.
