Underbody Coating

In Indian road conditions, a cars underbody is most prone to corrosion. 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.

1. Protects Against Rust & Corrosion

   The primary objective of getting underbody coating done is preventing metal components that are exposed on the bottom side of the car to damage from corrosion. You can shut out the Adverse effects of corrosion on your car by simply applying a rubberised anti-rust coating all over the belly of your car.

2. Reduces NVH (Noise Vibrations Harshness) Levels

   Our country is filled with roads having uneven patches and potholes and while we manoeuvre our cars through such sections, the unpaved crumbs, and pebbles hit the car from underneath or get stuck in the wheel wells. The underbody coating’s consistency is so thick that the layer it creates absorbs all the unpleasant noises and vibrations and marginally improves the driving experience.

3. Prevents Paint Chipping

   Running on the highway or while pacing through a city road, you will often encounter sharp gravel or any other unattended object hitting the belly of your car with high momentum. This scrapes and chips off the metal from down below. A thick layer of Underbody Coating definitely comes to aid and minimises the effects of such contacts on the body.

4. Protects Vital Components

   Underneath a car is somewhere a lot of indispensable parts of a car are left exposed like the Engine, silencer, etc. One simply can’t afford to let these parts go bad due to rusting and hence in order to save yourself from a hefty repair bill, a considerably less expensive Anti-Rust Coating is a must.

Why your car needs an underbody coating?

1. A must-have if you live in coastal areas

   Vehicles in the coastal areas are much more prone to corrosion than in any other region. The content of salt in the water floating around during the monsoon season is way too high. Adding to this is the humidity in such areas and these elements further speed up the process of corrosion. Hence getting your car done right with a nice underbody coat job is of utmost importance for people living that beach life.

2. Or if you live near un-paved/muddy roads

   If you live in areas having large sections of unpaved roads, then the monsoon is just going to make things worse. The sand is going to mix with the water and all that muck will get stuck to your car’s belly while you tread over such a course. This makes your car’s underbody more vulnerable to damage and a nice and thick coating will surely help.

3. It also affects your car resale value

   All that damage due to corrosion, if left unattended could lead to some permanent damage, which will cost you in terms of rapid depreciation in your car’s resale value. This will make it almost impossible for your car to pass a strict inspection when you put it up for sale. Hence, regular checks of your car’s underbody condition are the key to maintaining its value.

Now let us look at the various kinds of automotive underbody coating you can go for, for your vehicle.

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.

Benefits

• Minimizes Sound: It minimizes the sound from underneath the car resulting a 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.

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.
