Underbody Coating

UnderBody Coating

The Under body Coating is a protective layer applied to the BIW of the car to protect it against small stones, dirt etc. to damage the paint. It also helps in corrosion resistance of the metal and prevent rusting.

Types of under coating

1. Rubberized Under Coating

It 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. The coating can be painted over and, if necessary for bodywork, can be easily removed with an undercoating removal spray.

2. Polyurethane Undercoating

It is a type to use a polyurethane-based sealant. This type of vehicle undercoating is a little bit quicker and easier to apply.

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. 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 Under coating

It is wax/paraffin-based undercoating which will be the cheapest and quickest option available with which to protect the undercarriage of your vehicle. However, that it will wear off quicker than other types of undercoating and will need to be stripped and reapplied at least once every year.

4. Asphalt based Under coating

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. 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

Purpose of UnderBody Coating

• Provides general corrosion resistance to car body
• Increases the life of the car since it increases stopping power of rusting.
• Also , Protects the internal body panels, rails and other cavities which are prone to resistance
• It also acts to a extend of sounding proofing road noise against the inside cabin.
