Underbody Coating
What is Underbody Coating:
Underbody coating is nothing but to protect the metal sheet from corrosion, erosion, scratch, and other external causes by which sheet metal can be damaged. we apply a layer of paint with their thickness by which the Body in White (BiW) can be protected from external harmful effects.
Types of Underbody Coating:
- Rubberized Undercoating
Rubberized undercoating is easy to apply, and generally offers the best protective coating for your car’s undercarriage. It protects 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 undercarriage.
- 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.
Pros:
- Undercoating provides protection against rust and corrosion.
- Undercoating will extend the life of the vehicle
- It can be applied in damaged areas so that the vehicle parts can not be more damaged by rusting
- It reduces the interior noise
Cons:
- Undercoating is less effective if Rust and Corrosion is already present in vehicle body.
- If any person is purchasing any vehicle in every 3-5 years then Undercoating will useless for short-duration use of commodity and it will lead to increase in cost of vehicle.
- A third-party undercoating service will void the service warranty.
- Undercoating is add the extra weight in commodity.
