Step-by-Step Guide to Filling a Hole

1. Clean the area: Thoroughly clean the area around the hole with a degreaser and remove any loose rust or paint. This ensures proper adhesion of the body filler.
2. Prepare the filler: Mix the body filler and hardener according to the manufacturer’s instructions. Work quickly, as the mixture hardens relatively fast.
3. Apply the filler: Using a spreader, apply the filler to the hole, ensuring it fills the cavity completely and overlaps the surrounding metal slightly.
4. Sanding: Once the filler has cured, sand the area using progressively finer grits of sandpaper until smooth and flush with the surrounding surface.
5. Prime and paint: Apply primer to the repaired area, followed by several coats of paint that matches your car’s finish.
