Surface preparation is crucial for a successful Bondo application. Clean the area thoroughly with soap and water, then degrease it with a wax and grease remover. Sanding a Car Dent Before Applying Bondo Next, sand the dent and surrounding area with coarse grit sandpaper (around 80-grit) to create a rough surface for the Bondo to adhere to. Feather the edges of the sanded area to blend it seamlessly with the surrounding paint.

How Do You Clean the Dent Properly?

Use a good quality automotive soap and water. Rinse thoroughly and dry completely before moving on to the degreasing step. Any remaining dirt or grease can compromise the Bondo’s adhesion.

Mixing and Applying Bondo

Bondo comes in two parts: the filler and the hardener. Mix them according to the manufacturer’s instructions on a clean, non-porous surface like a piece of cardboard. Use a plastic spreader to apply the Bondo to the dent, working in thin, even layers. Allow each layer to dry and harden before applying the next. If you’re working with fiberglass, refer to our guide on fixing fiberglass cracks on car.

What Happens if You Mix Too Much Hardener?

Adding too much hardener will cause the Bondo to cure too quickly, making it difficult to work with. Follow the manufacturer’s instructions carefully for the correct ratio.

Sanding and Finishing

Once the final layer of Bondo has cured, sand it down with progressively finer grits of sandpaper, starting with 80-grit and working your way up to 400-grit or even finer. This process will smooth out the Bondo and blend it seamlessly with the surrounding body panel. After sanding, prime and paint the repaired area to match the rest of the car’s finish.
