Frequently Asked Questions

What is finishing film vs regular sandpaper?

Finishing film uses a uniform aluminum oxide grain bonded to a flexible film backing instead of paper. This produces a more consistent scratch pattern and finer finish — critical for clearcoat sanding where scratch marks would show through the final polish.

What grit for sanding clearcoat?

1000 grit is commonly used as a first step for wet or dry sanding clearcoat to remove orange peel, dust nibs, or runs. Follow with 1500 and/or 2000 grit before polishing for best results.

Dust free vs no holes — what's the difference?

Dust free discs (with holes) work with vacuum-equipped DA sanders for active dust extraction. No-hole discs provide a continuous abrasive surface and are used when vacuum extraction isn't needed.
