Body filler, also known as “Bondo,” is a type of automotive repair material that is used in body shops to repair dents, scratches, and other imperfections in car bodies. It is a two-part substance that consists of a resin and a hardener.

To use body filler, the damaged area of the car is first cleaned and prepared by sanding away any paint, rust, or other debris. The body filler is then mixed according to the instructions on the package, and applied to the damaged area in layers using a plastic spreader. Each layer is allowed to dry before the next one is added.

Once the body filler has fully cured, it is sanded down to create a smooth surface that is flush with the rest of the car’s body. The repaired area can then be painted to match the rest of the car.

Body filler is a common tool in automotive body shops because it is relatively easy to use and can effectively repair a wide variety of cosmetic damage. However, it is important to use the correct amount of filler and to properly prepare the surface to ensure a high-quality, long-lasting repair.
