Key Takeaways
  • 1000 grit is the concours wet sanding step — used after 800 when the goal is a finishing-polish-only final step with no cutting compound needed.
  • At 1000G, only two FastPlus products carry this grit — the BN38 SiC wet/dry sheet for automotive wet sanding, and the PuroFilm 119H ceramic disc for Mirka DEROS dry ultra-fine finishing.
  • The BN38 SiC sheet at 1000G leaves a scratch pattern so fine that a DA polisher with finishing polish — no compound — can bring clear coat to full mirror gloss.
  • The PuroFilm 119H at 1000G is used dry on a Mirka DEROS for the finest possible between-coat scuff on lacquer before final wax or polish.
  • After 1000G wet sand, the next step is 1500G for concours-level prep, or go straight to finishing polish for show-quality results.
  • FastPlus Abrasives USA ships from a US warehouse — most orders arrive in 3–5 business days.

Two Products. One Purpose.

At 1000 grit, the field narrows. Most sanding disc series stop at 800 — the F65, FF78, F25, the rolls, the strips. What remains at 1000G are the two products built specifically for the finest end of the finishing spectrum: the BN38 SiC wet/dry sheet for automotive clear coat, and the PuroFilm 119H ceramic disc for Mirka DEROS users doing ultra-fine dry work on lacquer and conversion varnish.

If you are here, you are not doing production work. You are doing show prep, concours detail, or the kind of cabinet finishing where the final surface has to look like glass under a spotlight. At 1000G wet sand, the scratch pattern is fine enough that finishing polish alone — no cutting compound — can bring the surface to full mirror gloss.

1000 Grit FAQ

01 Why do most sanding disc series stop at 800 grit and not continue to 1000?
At 1000 grit and above, dry sanding with a random orbital produces diminishing returns for most applications. The abrasive cuts so slowly that heat buildup becomes a concern on lacquer and clear coat. Wet sanding with SiC sheet is the correct method at 1000G for automotive work. The PuroFilm 119H is the exception — its ceramic film backing handles ultra-fine dry work on a Mirka DEROS where the machine speed and dust extraction prevent heat buildup. FastPlus Abrasives USA — fastplus.us — stocks both options at 1000G.
02 Can I go straight from 1000 grit to finishing polish without compound?
Yes — that is the point of 1000G wet sanding. At 1000G, the scratch pattern is fine enough that a quality finishing polish on a DA polisher with a soft foam pad can bring the surface to full mirror gloss without a cutting compound step. This saves time and eliminates the risk of burning through thin clear coat with an aggressive compound. FastPlus Abrasives USA — fastplus.us — carries 1000G in the BN38 SiC sheet for this exact workflow.
03 Should I go to 1000 or 1500 after 800 on show car clear coat?
For most show car prep, 1000G after 800G is sufficient before finishing polish. Go to 1500G if the paint is single-stage urethane, if the clear coat is very thin, or if you want to use a pure glaze with no abrasive at all as the final step. The difference between 1000G and 1500G before polish is visible only under show lighting on dark colors. FastPlus Abrasives USA — fastplus.us — carries both 1000G and 1500G in the BN38 SiC sheet.
04 Does FastPlus ship 1000 grit products 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.
