Underbody Coating

Underbody Coating

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.

The main purpose of undercoating is to check rust especially in the body components like frame rails along with other exposed metal parts.

Underbody coating can also reduce wear and tear

Benefits

1. Minimizes Sound - It minimizes the sound from underneath the car resulting a noiseless, smooth driving experience.
2. Heat Insulation - It insulates the interior of the car from extreme temperatures from beneath the vehicle providing a comfortable cabin experience.
3. Anti-chipping property - If any stone hits the coating it does not get chipped away hence protects the underbody from exposure to water.

Types of Underbody Coating

Having undercoating professionally applied to your vehicle can be expensive, but fortunately, if your budget is tight, you can do it yourself for a fraction of the price. Here are some of the various types of undercoating available.

1)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.
• The coating can be painted over and, if necessary for bodywork, can be easily removed with an undercoating removal spray.
• Overall, rubberized is generally the best option for protecting your vehicle's undercarriage, as it provides the simplest and best protective measures against rust and moisture.

2)Polyurethane Undercoating

• This type of vehicle undercoating is a little bit quicker and easier to apply.
• Oftentimes, polyurethane undercoating will come in canisters ready to 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 unoxidized metal.
• It also sands quickly in case you'll need to perform bodywork and can be painted over.
• On the flipside, this type of car undercoating generally requires a little bit more surface prep work before applying -- sanding and applying an etching primer to bare metals before using are generally recommended.

3)Wax or Paraffin-Based Undercoatings

• 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.
• Wax-based undercoatings never truly harden. During application, they drip or flow into seams and cracks to provide protective properties.
• They are usually available in a spray gun canister or in an aerosol can and offer at least a base protection in moderately humid climates.

4)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.
• Asphalt-based undercoating generally contains a little bit of rubberized material that sets up firmly and also helps soften noise.
• Generally sold in five gallon containers, this type of undercoating also needs more cure time than the other three, and is not paintable, making it best to use only for undercarriages.

Pros of Undercoating

• The pros of undercoating are the protection it provides to the carriage of your vehicle.
• Undercoating gives you an extra layer of protection against rust and corrosion, protecting your car.
• Undercoating will eventually wear out, but you can get years of protection from it. Even vehicles in warmer climates gain protection as debris is repelled and kept away from heating at the vehicle.

Cons of Undercoating

• Undercoating will work best on new vehicles that have not been exposed to road conditions.
• A used vehicle may already have residue on the bottom of the car or even have spots of rust and corrosion.
• 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 us.
