Frequently Asked Questions

What is finishing film vs regular sandpaper?

Finishing film uses uniform grain on a flexible film backing, producing a more consistent scratch pattern — critical for clearcoat sanding where finish quality matters.

What grit for sanding clearcoat?

Start with 1000 or 1200 grit to level the surface, then 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. No-hole discs provide continuous abrasive contact for wet sanding or without vacuum.
