How to Use (Step-by-Step)

1. Step 1: Prepare the Surface: Clean the area to be repaired thoroughly. Remove any rust, loose paint, or debris. Sand the surface with coarse sandpaper (e.g., 80 grit) to create a good bonding surface.
2. Step 2: Mix the Filler: Place a small amount of polyester filler on a clean, non-porous mixing board. Add the hardener (typically a few drops per golf ball-sized amount of filler, refer to the hardener instructions for ratio). Mix thoroughly until a uniform color is achieved. Do not mix more than you can use in a few minutes, as the filler will begin to harden.
3. Step 3: Apply the Filler: Using a plastic spreader, apply the mixed filler to the prepared surface. Press firmly to ensure good adhesion. Fill any dents or holes completely. Apply in thin layers if necessary to avoid air pockets.
4. Step 4: Allow to Cure: Let the filler cure completely according to the hardener instructions. This usually takes 20-30 minutes, depending on temperature and humidity. The filler should be hard to the touch.
5. Step 5: Sand the Filler: Once cured, sand the filler to the desired shape and smoothness. Start with medium-grit sandpaper (e.g., 180 grit) to remove any excess material and shape the repair. Finish with fine-grit sandpaper (e.g., 320 grit) to create a smooth, paint-ready surface.
6. Step 6: Clean and Paint: Remove all sanding dust from the repaired area. Apply primer and paint according to the paint manufacturer's instructions.
