Underbody Coating
UNDERBODY COATING
Underbody coating means a coating, used at an automobile or light-duty truck assembly coating facility, applied to the undercarriage or firewall to prevent corrosion and/or provide chip protection.
Under-Body Coating Purpose:-
It provides longterm protection from corrosion to car's Underbody. It also protects arts like internals 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 our top priority, especially during monsoon when heavy precipitation causes the roads to become mini rivers our cars are left standard there. This makes them prone to heavy corrosion in the underbody region.
It protects from ;
- Environmental Condition
- Dampen sound and vibration
- Impacts
- Protects against corrosion
- Seal off seams
- Insulated against cold and heat
- Hides welds, repair and bodywork with spray
Types of underbody coating:
- Rubberized Undercoating
- Polyurethane Undercoating
- Wax or Paraffin Based Undercoating
- Asphalt-Based Undercoating
1.Rubberized Undercoating
It is easy to apply and offers sound cushioning as well as protection from dust, moisture, and dings or dents. In addition undercarriage rubberized undercoating in also safe to use on wheel wells and quarter panels and dries to a soft rubbery finish prevents further rust damage or moisture seeps. The coating can be painted over necessary for bodywork can be easily removed with an undercoating removal spray.
2.Polyurethane Undercoating
The other option for undercoating your vehicle is to use polyurethane based sealant, this type of vehicle undercoating is a little bit quicker and easier to apply. Polyurethane undercoating will come in canister preload into an application gun. This type pf 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. It also sands quickly in case you'll need to perform bodywork and can be painted over.
3.Wax or Paraffin Based Undercoating
A paraffin based undercoating will be the cheapest and quickest option available with which to protect the under carriage 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.
4.Asphalt-Based Undercoating
In standard vehicle any of the aforementioned type undercoating will provide sufficient protection. For large trucks and heavy machinery, asphalt based undercoating provide bit of extra durability against rocks. Generally contains a little bit of rubberized material that sets up firmly and also helps soften noise. Sold in five gallon containers, this type of undercoating also needs more cure time than the other three and NOT paintable making.
Pros :-
1. Provides an Extra Layer of Protection
2. Extends the Lifetime of Your Vehicle
3. Reduces Internal Noise
4. Comes with Several Undercoating Methods
Cons :-
- Less Effective If Corrosion Already Exists
- Works Well on New Vehicles
- Not Impervious to Damage
- Need to Reapply Every 3 to 5 Years
