Underbody Coating
INTRODUCTION:
* In indian road conditions ,a car underbody is most prone to corrosion .underbody coating provides long term protection from corrosion to car underbody .it also protects parts like internal body paneals frame rails and other inner cavities that are not physically accessible but are prone to corrosion.
UNDERBODY COATING:
* Underbody coating its usually a dense cladding(often based on rubber) applied uniformly to the undercarriage of the automobile.it is normally sprayed or painted on when th car is just out of the delarship and is clean
* But even if you are getting the undercoating applied after a couple of years fine too.
* Ideally any additional underbody coating should be applied when the car is brand new and clean .car manufacture use thick paints and sealants for the underbody but adding an underbody code especilly in coastal cities is useful.
IT PROTECTS THE UNDERBODY :
* Environmental conditions
* Impacts
* Dampens sound and vibrations
* Insulates against cold and heat
* Protects against corrosion
* Hides welds ,repairs and bodywork with spray
TYPES:
* RUBBERIZED UNDERCOATING
*POLYURETHANE UNDERCOATING
* WAX AND PARAFFIN -BASED UNDERCOATING
* ASPHALT -BASED UNDERCOATING
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 a well and quarter panels and dries to a soft rubbery finish thats 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 apply
* Oftentime 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 area to bond with and protect unoxidized metal.
* On the flipside this type of car undercoating generally requires a little bit more surface prep work before applying -sanding and applying at etching primer to bar metals.
WAX OR PARAFFIN -BASED ON UNDERCOATING:
* A paraffin -based on undercoating will be chepest and quickest option available with which to product 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.
UNDERBODY COATING :
PROCESS:
* When it comes to updating your vehcile or using any sort coating ,remove the rust completely first and then preoess .rust removal is easialy achieved by snadblasting or sanding ,depending on the area and the extant of the rust.
* Once you removed the rust and prepped your undercarriage for coating ,gives it a quick rines and let it dry to ensure you arn't further tripping any containminatnts on your vehcies underbelly.using a degrester to clean the metal first is also recommended.
* Most undercoating is generally applied with a spray gun.a diposable spray gun will work best once the undercoating hardnes it becomes very difficult to clean the gun even with lot of thinner .
PROS:
Minimize sound:It minimize the sound from underneath the car resulting a noiseless smooth driving experience .
Heat insulation: It insulates the interior of the car from extreme temperature from beneath the vehcile providing a comfortable cabin experience .
Anti -chipping property: If any stone hits the coating it does not get chipped away hence protects the underbody from exposure to water.
CONS:
* Apllying underbody coating will not have any effect to the already corroded part .
* undercoating its costly.
