Types of Body Filler for Cars

Polyester Body Filler

Polyester body filler is the most common type of body filler used for cars. It is made of a polyester resin and a filler, such as fiberglass or talc. Polyester body filler is strong and durable, and it can be sanded and painted to match the rest of the car’s body. However, polyester body filler can shrink over time, so it is important to use it sparingly.

Epoxy Body Filler

Epoxy body filler is a two-part epoxy that is mixed together before being applied. Epoxy body filler is stronger and more durable than polyester body filler, and it does not shrink over time. However, epoxy body filler is also more expensive than polyester body filler.

Urethane Body Filler

Urethane body filler is a newer type of body filler that is made of a urethane resin and a filler. Urethane body filler is strong, durable, and flexible, and it can be sanded and painted to match the rest of the car’s body. Urethane body filler is also less likely to shrink over time than polyester body filler.

Which Type of Body Filler Should You Use?

The best type of body filler for your car will depend on the specific repair that you are doing. If you are repairing a small dent or scratch, polyester body filler will probably be sufficient. However, if you are repairing a larger area, such as a rusted-out panel, you may want to use epoxy or urethane body filler instead.

How to Apply Body Filler

To apply body filler, you will need to first clean the area that you are repairing and then sand it to create a smooth surface. Once the surface is prepared, you can mix the body filler according to the manufacturer’s instructions. Apply the body filler to the damaged area using a putty knife or spreader. Once the body filler has been applied, you can sand it to shape and smooth it out. Finally, you can paint the body filler to match the rest of the car’s body.

• Use a clean putty knife or spreader to apply the body filler.
