Who Is This For?

  • Auto body technicians wet sanding clear coat, lacquer, and primer by hand
  • Car detailers removing orange peel, paint runs, and water spots from clear coat
  • Metal finishers polishing aluminum, stainless steel, and chrome to a mirror finish
  • Woodworkers doing final wet sanding on lacquer and varnish before buffing
  • 3D print finishers wet sanding resin and PLA parts to remove layer lines
  • Anyone needing a full grit range P80–P2000 in a single versatile sheet format

For orbital sander wet sanding, use waterproof PuroFilm 6" film discs instead — hook-and-loop attachment is faster for machine use.

Compatible Applications

  • Hand sanding — cut to size, wrap around a sanding block or use bare hand for curved surfaces
  • Wet sanding — fully waterproof latex backing, use with water or soapy water as lubricant
  • Dry sanding — works dry on wood, metal, and primer at P80–P400
  • Sanding blocks — cut to fit any standard hand sanding block
  • Spot repair — cut small pieces for targeted clear coat correction

Sheet size: 9"×11" (230mm×280mm) — standard size fits all hand sanding blocks and can be quartered for spot work.

Grit Selection Guide

Grit Use Case Wet or Dry
P80–P120 Strip paint, remove rust, shape filler Dry
P180–P320 Sand primer, prep metal before painting Dry or wet
P400–P600 Denib paint, sand between coats Dry or wet
P800–P1000 Wet sand clear coat, remove orange peel Wet recommended
P1500–P2000 Pre-polish wet sanding — most popular range Wet only

Wet sanding tip: Add a drop of dish soap to water as lubricant — reduces friction, keeps surface cool, and flushes swarf away. Follow P1500–P2000 wet sanding with FlexPro Foam Discs P3000–P5000 for final machine polishing. Related guide: How to Wet Sand Car Clear Coat
