3M Wet or Dry Sandpaper uses sharp silicon carbide grain on a waterproof backing, so you can sand wet to flush away swarf or dry for fast cutting. Very Fine grit is the prep-and-feather grit for body work - smoothing bondo edges, prepping primer for paint, and breaking the gloss on existing finishes before recoating.

• Silicon carbide grain - sharp, fast-cutting, smooth finish
• Waterproof backing for wet sanding; reduces clogging and dust
• 9" x 11" full sheets - tear into thirds or quarters for pad sanders
• Between-coat sanding for varnish, paint, and clear finishes
• Wet-sand bare metal before primer to smooth and clean in one step
• 5 sheets per pack

Tip: Wet sand using long, straight strokes in one direction - circular motion at this grit can leave swirls that show through topcoat.
