5. Sanding – Once hardened, sand with P80-P180 grit sandpaper for a smooth finish.

2. Can I apply U-POL P38 filler over paint?

Yes, but for best results, it is recommended to apply it on bare metal or properly primed surfaces. If applying over paint, ensure it is clean, scuffed, and free from contaminants.

3. Is this filler waterproof?

U-POL P38 is not fully waterproof but highly resistant to moisture. If using in marine applications, it should be sealed with a primer or waterproof coating.

Start with P80-P120 grit for initial shaping, then finish with P180-P240 grit for a smooth surface.

7. Can this filler be used for deep dents?

For deep dents and large holes, it is best to apply in layers to prevent excessive shrinkage. Build up in thin layers rather than one thick application.

Once mixed with the hardener, the working time is approximately 4-5 minutes, so apply quickly before it sets.
