What 800 grit is for
800-grit (also sold as P800) is a specialized auto-body and metal-finishing grit. It’s the standard wet-sanding grit between primer and color coat in automotive paint work, and the intermediate step in most metal-polishing sequences.
Projects at 800 grit
- · Wet sanding auto primer before color coat
- · P800 intermediate step on stainless steel polishing
- · Smoothing imperfections on cured clear coat
- · Pre-polish on cured powder coat repairs
- · Knife edge refinement on hand-forged blades
Abrasive materials
- · silicon carbide (overwhelmingly the standard at this grit)
- · aluminum oxide (less common, dry use only)
Common mistake
P800 (CAMI 800) and FEPA P800 are nearly identical, but other CAMI vs. FEPA grits diverge above 220. Check the spec on the packaging.
