Underbody Coating
UNDERBODY COATING:
underbody coating is a sprayable coating, which protects the under surface of the vehicle from corrosion.
underbody coating provides long term protection from corrosion to cars underbody. It also protects part like internal body panels, frame rails and other inner cavities that are not physically accessible but are prone to corrosion.
protecting the underbelly of the car should be out top priority. Especially during monsoon when heavy precipitation causes the roads to become mini-rivers and our cars are left stranded there. This makes them prone to heavy corrosion in the underbody region.
it protects the underbody substrates from:
*environmental conditions
*Impacts
*dampens sound and vibration
*insulates against cold and heat
*protects against corrosion
*seals off seams
*hides welds, repairs & bodywork with spray.
Types:
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 body work, can be easily removed with an undercoating removal spray.
overall, rubberized undercoating is generally the best option for protecting your vehicles undercarriage,as it provides the simplest and best protective measure against rust and moisture.
POLYURETHANE UNDERCOATING:
the other option for undercoating your vehicle is to use a polyurethane based sealant. This type of sealant works by seeping into all cracks and seams, displacing salt and moisture and oozing around rusty area to bond with protect unoxidized metal. It also sand 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 premier to bare metals before using are generally recommended.
Wax or Paraffin- based undercoating:
A paraffin based undercoating will be the cheapest and quickest option avaliable wit which to protect the undercarriage of your vehicle. Howeve, keep in mind that it will wear off quicker than other types of undercoating and will need to be supplied and reapplied every year.
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.
PROS-
*Minimizes sound: it minimizes the sound from underneath the car resulting a noseless, smooth driving experience.
CONS-
*undercoating is costly
*Applying underbody coating will not have any effect to the already corroded part.
*since the corrosion itself start after few year, underbody coating is not preferable to owner who change their car after few years.
