Underbody Coating
Underbody Coating
India has very diverse weather conditions and different types of terrains. In monsoon season or in coastal areas the underbody of the car gets corroded due to dirt and humidity which needs care to be taken. Since the underbody of car is difficult to inspect we need underbody coating to ensure car gets protection from corrosion. Here is list of other factors that also gets effected by underbody coating.
Protection against corrosion
The main reason for doing underbody coating is to prevent the car from corrosion due to monsoon and dirt. But also, from humid climate conditions in coastal area which increases the rate of corrosion.
Protection of vital car components
The underbody of any car has vital components like the silencer, engine, axles, suspension system, transmission system, wires and other engine component which need to be taken care of from rusting, so the antirust coating is necessary.
Car’s resale value might be affected
While reselling of car only ensuring inner and outer body looks is not enough. The underbody of the car is also important factor which plays keys role while calculating value of the car. Rusted underbody can affect the cost and make huge loss while reselling.
Reduces NVH (Noise Vibration Harshness) levels
While traveling the car goes from bumpy roads, path holes, stones, debris, and uneven road levelling which crates noises and vibrations. The underbody coating absorbs these vibrations and sounds and improve experience of driving.
Car underbody coating prevents paint from chipping
When car travels with high speed on highways the small stones and debris hit the underbody of the car and this may lead to chipping of underbody paint. So, it is advisable to go for an underbody coating with thick layer to protection from paint chipping.
Different Types of Vehicle Undercoating
Here are some of the various types of undercoating available.
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 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.
Polyurethane Undercoating
This type of vehicle undercoating is a little bit quicker and easier to apply. Often polyurethane undercoating will come in canister ready to preload into an application gun. This type of sealant works by seeping into all cracks and seams, displacing salt and moisture and seep out 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.
Wax or Paraffin-Based Undercoating
A paraffin-based undercoating will be the cheapest and quickest option available with which to protect the undercarriage of vehicle. 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 undercoating 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.
Asphalt-Based Undercoating
For standard vehicles, any 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. This type of undercoating also needs more cure time than the other types, and is NOT paintable, making it best to use only for undercarriages.
