Step-by-Step Instructions
1. Prepare the Work Area

3. Apply the Filler
* Use a spatula to apply the filler to the damaged area.
* Spread the filler evenly, working from the center outwards.
* Build up the filler in layers, allowing each layer to dry before applying the next.
4. Shape the Filler
* Once the filler is dry, use sandpaper to shape it.
* Start with coarse-grit sandpaper to remove excess filler.

Tips
