Underbody Coating

UNDERBODY COATING:

Underbody Coating is a sprayable coating, which protects the undersurface of the vehicle from corrosion. Underbody coating provides long-term protection from corrosion to the car's underbody.

Types of underbody coating:

• Rubberized undercoating: Rubberized Undercoating is easy to apply and offers sound cushioning as well as protection from dust, moisture, and dings or dents. In addition to your undercarriage, rubberized undercoating is also safe to use on wheel wells and quarter panels, and dries to a soft rubbery finish that prevents further rust, damage, or moisture seeps.
• Polyurethane Undercoating: The other option for undercoating your vehicle is to use a polyurethane-based sealant. This type of vehicle undercoating is a little bit quicker and easier to apply.Oftentimes, polyurethane undercoating will come in canister preload into an application gun. This type of sealant works by seeping into all cracks and seams, displacing salt and moisture and oozing around rusty areas to bond with and protect un-oxidized metal.
• Wax or Paraffin-Based Undercoating: A paraffin-based undercoating will be the cheapest and quickest option available with which to protect the undercarriage of your vehicle. However, keep in mind that it will wear off quicker than other types of undercoating and will need to be stripped and reapplied at least once every year.
• Asphalt-Based Undercoating: For standard vehicles, any of the aforementioned types of undercoating will provide sufficient protection. For large trucks and heavy machinery, asphalt-based undercoating provides a bit of extra durability against rocks, chips, and moisture.

Process-

• When it comes to updating your vehicle or using any sort of coating, remove the rust completely first and then proceed. Rust removal is easily achieved by sandblasting or sanding, depending on the area and the extent of the rust.
• Once you've removed the rust and prepped your undercarriage for coating, give it a quick rinse and let it dry to ensure you aren't further trapping any contaminants on your vehicle's underbelly. Using a degreaser to clean the metal first is also recommended.
• Most undercoating is generally applied with a spray gun. A disposable spray gun will work best; once the undercoating hardens, it becomes very difficult to clean the gun even with a lot of thinner. A Schultz disposable spray gun is the best option.
• No matter what type of vehicle undercoating you've selected, two coats will provide the optimum protection. Allow ample dry time between coats.
• Let the undercoating cure completely (usually overnight) before driving your vehicle on the road.

Pros-

• Minimizes Sound: It minimizes the sound from underneath the car resulting in 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 protecting the underbody from exposure to water.

Cons-

• Applying underbody coating will not have any effect on the already corroded part.
• Undercoating is costly.
• Since the corrosion itself starts after a few years, underbody coating is not preferable to ower who change their car after a few years.
