Underbody Coating
UNDERBODY 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.
TYPES-
-
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.
ADVANTAGE-
-
It extends the lifespan of your car-The protection against rusting gives you the biggest advantage, which is the long-life of the vehicle. If undercoating is done the right way, then it will provide protection for up to 10 years. In some cases, the time span is more than ten years, which extends the lifespan of your vehicle.
-
No more loud road noise-The undercoating serves as an extra layer of insulation, reducing the noise from penetrating inside components. Thus padding acts as a barrier between you and the source of the noise. If the road noise bothers you while driving your car, truck, or SUV, then applying to undercoat can help you.
DISADVANTAGE-Nothing comes for free in this world. The same goes for undercoating. 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.
