Underbody Coating
UNDER BODY COATING
It is the coating of a formulated layer which is uniformly applied usually sprayed or painted on the undercarriage of the automobile, the inside of the door panels, fender and hood of the motor vehicle to prevent it from damage and rusting.
TYPES OF UNDERCOATING
Rubberized Undercoating
- This type of undercoating is easy to apply and offers sound-cushioning as well as protection from dust, moisture, and dings or dents.
- 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.
- Overall it is the best option for protecting your vehicle's undercarriage, as it provides the simplest and best protective measures against rust and moisture.
Polyurethane Undercoating
- Polyurethane based sealant vehicle undercoating is a little bit quicker and easier to apply. 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 oxidized metal. It also sands quickly in case you'll need to perform bodywork and can be painted over.
- It requires a little bit more surface prep work before applying -- sanding and applying an etching primer to bare metals before using are generally recommended.
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.
- It will wear off quicker than other types of undercoating and will need to be stripped and reapplied at least once every year.
- 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.
Asphalt- Based Undercoating
- Used on 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.
- 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.
ADVANTAGES OF UNDERCOATING
- 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.
- Absorbs noise: 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
- Reinforcement: 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.
- It prolong car 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.
- Heat insulation
- Anti-chipping property
DISADVANTAGES OF UNDERCOATING
- Comparatively expensive.
- Undercoating will work best on new vehicles that have not been exposed to road conditions.
- Undercoating will not help you if corrosion already exists and the corrosion needs to be removed first before it can be applied, which is again expensive.
