What P2000 is for

The last paper step before compound on most paint.

Holding US-marked paper instead? The size match is CAMI 1000: 3M Wetordry 1000 (read as CAMI, per the note on that chart).

Questions people ask

What is P2000 in CAMI grit?

About 1000. P2000 averages 10.3 microns on the FEPA table and CAMI 1000 averages 10.3, so the scratch is close to the same.

How many microns is P2000 sandpaper?

About 10.3 microns average particle diameter, per the FEPA P-grade table (ISO 6344).

Sizes are average particle diameters from the published FEPA (ISO 6344) and CAMI (ANSI B74.12/B74.18) tables. "Nearest" means within 10%; otherwise both neighbors are shown. Trizact pairings are 3M's own. Sources: Wikipedia, "Sandpaper" grit table (rev. 1127917881); Klingspor coated abrasives grit chart.
