Underbody Coating

What is undercoating?

Undercoating is the sprayed application of a wax or rubber-based composite onto the entire underside of the vehicle. It's designed to create a rust-proof layer between the underside of the vehicle and the water, ice, and salt of the road. Undercoating provides a more comprehensive protective layer for your vehicle.

The purpose of undercoating

1. Keeps away rust and corrosion

Just because a car has been in use for a while doesn’t mean it’s already damaged underneath by rust and corrosion beyond repair. Some drivers are very careful to keep their cars clean and crack, rust, and corrosion-free. Undercoating such used cars add a much-needed protective layer for the undercarriage, especially since one can protect their car from rust for only too long.

2. Protects deadly damaged areas under the car

If your car has already been damaged by rust and corrosion from years-long use on icy roads and endless rounds of rust formation, it can still be saved by undercoating. When done right, undercoating involves an initial clean-up process that rids the undercarriage of any accumulated gunk, rust, and dirt. The new clear undercarriage is then primed with a new protective layer of undercoating, paving the way for a fresh start and protecting the areas that were already damaged.

3. It could help lower your overall auto premium

Undercoating is essentially one way of giving your car a proactive service, which in turn reduces the risks of a claim on your auto insurance. In other words, when done right, you’ll end up paying less on your premiums. This works well in states and countries with noted high levels of corrosion.

4. Improves overall exterior appearance

An undercoated car looks way better than the average car, and that’s because undercoating covers up all paint scratches, cracks, nibs, rust circles, and more than the car might have heard. Undercoating can be painted on for an even better exterior look. Rustproofing your car on your own is the cheaper way to go.

Types of Undercoating

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.

Pros of Undercoating

1. 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.

2. Absorbs Noise

Believe it or not, very thick undercoating can soften the noises that reach the cabin. Since the undercoating is often made up of rubber it absorbs some of the rackets. The occupants of the car could spare themselves of the road noises – at least up to a certain extend.

3. Reinforcement

If your car comes with stock underbody coating, using another coating on top of it, is not going to hurt. It will offer additional reinforcement, protecting the underbody from water, road debris, gravel and small pebbles. There would also be a lesser chance for the factory coat to flake away.

4. Prolong Car’s Life

Good undercoating not only defends the underbody from corrosion but also protects the engine and transmission as well! Less rusting coupled with slower wear and tear can surely add years to the lifespan of your vehicle. There would be fewer dents, dings and scratches on the undercarriage for you to fret about.

Cons of Undercoating

1) Undercoating will work best on new vehicles that have nothing been exposed to road conditions.

2) A used vehicle may already have residue on the bottom of the car or even have spots of rust and corrosion.

3) Undercoating will not help you if corrosion already exists and the corrosion needs to be removed first before it can be applied, which can be expensive for you.
