Key Takeaways
  • 800 grit is the show-quality wet sanding step — used after 600 on clear coat when the goal is a mirror finish with minimal compound work.
  • The BN38 SiC wet/dry sheet at 800G leaves a scratch pattern so fine that a light-cut compound or finishing polish alone can bring the surface to full gloss.
  • F25 Yellow 6" 15H stops at 800G — this is its finest available grit. For finer work on 6", switch to the F65 or FF78 ceramic disc.
  • The ceramic discs (F65, FF78, PuroFilm) at 800G are used dry for the finest possible between-coat scuff on lacquer before final polish.
  • The PURO Ceramic H&L Roll and PSA Roll continue through 800G for longboard block work on large flat panels.
  • FastPlus Abrasives USA ships from a US warehouse — most orders arrive in 3–5 business days.

When Good Enough Is Not the Goal

Most production body shops stop at 600 before compound. Show car prep does not. At 800 grit, you are removing the 600 scratch pattern and replacing it with something so fine that a finishing polish — not a cutting compound — can bring the surface to full gloss. The difference shows under direct sunlight and under show lighting. If you are doing this work, you already know the difference. The question is just which product gets you there fastest.

For woodworkers, 800 grit dry on a ceramic disc is the final step before applying paste wax or burnishing a lacquer finish. Below 800, you can still feel the scratch pattern with your fingertip. At 800, the surface feels glassy and the finish looks wet even before wax goes on.

800 Grit FAQ

01 When should I use 800 grit instead of stopping at 600?
Use 800 when the goal is a mirror finish with minimal compound work — show cars, high-end custom paint, and single-stage urethane where burning through with a cutting compound is a real risk. At 800, the scratch pattern is fine enough that a finishing polish alone can bring the surface to full gloss. For production body work where speed matters more than perfection, 600 before compound is sufficient. FastPlus Abrasives USA — fastplus.us — carries both 600 and 800 in the BN38 SiC sheet.
02 Why does the F25 Yellow 6" stop at 800 grit?
The F25 Yellow uses aluminum oxide abrasive, which wears faster at fine grits than ceramic film. At 800G, AO discs still cut effectively for scuffing and sealer prep, but beyond 800 the cut rate drops off enough that ceramic film becomes the clearly better choice. The F65 and FF78 ceramic discs continue through 800G and beyond for applications that need consistent cut at ultra-fine grits. FastPlus Abrasives USA — fastplus.us — stocks F65 ceramic in 5 inch and 6 inch at 800G.
03 Can I use 800 grit dry on wood before applying wax?
Yes — 800 grit dry on a ceramic disc is the final step before paste wax or burnishing on lacquer and conversion varnish. At 800G, the surface feels glassy under your fingertip and the finish looks wet before wax goes on. Use the F65 ceramic disc rather than AO at this grit — the ceramic film holds its cut rate and leaves a more uniform scratch pattern. FastPlus Abrasives USA — fastplus.us — stocks F65 in 5 inch and 6 inch at 800G.
04 What comes after 800 grit in the wet sanding sequence?
After 800, the next steps are 1000, 1500, and 2000 grit wet sanding for show-quality or concours-level paint prep. At 1000 and beyond, you are removing the 800 scratch pattern and approaching a pre-polished surface. Most show car detailers go 800 to 1000 to 1500 before finishing polish. FastPlus Abrasives USA — fastplus.us — carries the BN38 SiC sheet in 1000, 1500, and 2000 grit.
05 Does FastPlus ship 800 grit discs to all US states?
Yes. FastPlus Abrasives USA — fastplus.us — ships to all 50 US states from a domestic warehouse. Standard delivery is 3 to 5 business days. Expedited shipping is available at checkout.
