Underbody Coating

Underbody Coating:

Underbody coating is a thick resilient coating applied to the underbody or chassis of an automobile to protect against impact damage from small stones, which could rapidy chip with ordinary paint allowing rusting to begin. This coating helps in protection from dust and moisture and some other factors such has poor road conditions. Especially during monsoon seasons due to water stagnation on roads our cars are left stranded in water which causes heavy corroision in the underbody.

Benefits of Underboady Coating:

1) 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.

2) 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.

How to undercoat your Car?

You have a few options to select from while considering an undercoating for your vehicle. Obviously, if you are getting it done through an authorized dealer, then you would have no choice as they have their own preferences.

1) Spray

The spray is the most common method used by dealers. The spray consists of a tar-like substance that is applied to the undercarriage. It functions as a barrier for salt, moisture, and oxygen, which causes corrosion.

2) Electronic

Removing the electrical current capacity of items underneath the vehicles is another method for applying to undercoat. A weak electric current circulates through the material, reducing the chances of rusting.

3) Drip Oil Spray

If you want to do it yourself, then drip oil spray is the best option. This can be messy but incredibly effective at protecting the undercarriage. It covers every nook and corner of the chassis, forming a robust layer of protection.

Time is the factor where you have to show patience in this method. It takes a long time to dry. In some cases, it drips around 48 hours to a week.

4) Dripless Oil Spray

Coming to the last option, the dripless oil spray. This waxy substance is applied to the body and undercarriage, forming a strong protective layer. It doesn’t take much time to dry; however, the layer can easily wear and tear than the other counter methods.

Types of Underboady coating:

Rubberized Undercoating

Rubberized undercoating is easy to apply, and generally offers the best protective coating for your car’s undercarriage. It cushions surfaces against moisture, rust, dings, and dents. Rubberized undercoating is safe to use on quarter panels and wheel wells and dries with a soft rubbery finish.

Asphalt-Based Undercoating

Asphalt-based undercoating offers a higher level of protection suitable for large trucks, recreational vehicles, and heavy machinery. It’s formulated with some bits of rubberized material to aid in noise reduction. It offers extra protection against chips and moisture but is not paintable and, therefore, only suitable for undercarriages.

Polyurethane Undercoating

Polyurethane coating is easy to apply and works by sealing up cracks and seams. The compound displaces salt and moisture and protects the unoxidized metal from rust. It’s often sold in canisters that are ready to preload into an application gun. It, however, requires some surface prep work before application, like degreasing, and applying an etching primer to the bare metal.

Wax or Paraffin-Based Undercoating

Wax or paraffin-based undercoating sprays are the cheapest and quickest options available. However, their results don’t last long, and you may have to apply a fresh coat after only a few months. In addition, the wax isn’t very adhesive on a metal surface. Its main advantage is that it seeps quickly into cracks and seams, and offers moderate protective properties against moisture.

Most of the vehicles manufactured these days are rust proofed, especially in rainy and cold regions. When your car is exposed to saltwater and other common electrolytes, investing in an undercoating from an authorized dealer is a smart investment. It does cost a few hundred dollars, but it’s worth it. It will keep your ride in good condition for five years.

PROS OF UNDERBODY COATING:

• 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.

CONS OF UNDERBOADY COATING

• Underboady Coating is expensive
• Underbody coating is difficult on used vehicle because it is exposed to road conditions and will have spots of rust and corrosion. The corrosion needs to be removed first before it can be applied,which can be expensive.
