320 Grit Wet/Dry Sandpaper for Finishing
This box contains 25 sheets of 320 grit silicon carbide sandpaper measuring 9 by 11 inches. The resin-bonded abrasive is designed for wet sanding between coats of paint, sealer or varnish. It suits automotive and woodworking finishing tasks where a very fine surface is required.
Wet-sanding limits and sheet durability
The silicon carbide grains cut under water or solvent without loading as quickly as dry-only paper. Resin bonding keeps the grit attached longer than glue-bond alternatives when the sheet is soaked. Sheets wear faster on bare metal than on primer or clear coat, so progress should be checked often.
Check grit sequence and sheet count before ordering
Verify that 320 grit fits the abrasion stage you have reached; coarser grades such as 120 or 180 remove material faster, while 400 leaves a finer scratch pattern. Confirm that 25 sheets per box matches the project size, because the pack cannot be split into smaller quantities.

Questions about this item
Which grit should I choose between the 120, 150, 180, 220, 320 and 400 versions?
Start with 120 or 150 for heavy material removal and body leveling, move to 180 or 220 for finer surface prep, use 320 for smoothing primers between coats, and finish with 400 for the finest surface before topcoat.
How does the 320 grit perform when sanding between coats of paint or varnish?
The 320 grit is graded very fine and designed for smoothing primers, sealers and varnish between coats; the silicon carbide abrasive cuts cleanly wet or dry and the resin bond resists loading so the paper lasts through multiple passes.
What backing size and pack quantity does the 4240 model use?
Each sheet measures 9 by 11 inches and the box contains 25 sheets, giving enough area for large panels while the box keeps the sheets flat and protected until needed.
