Key Takeaways
  • 1500 grit is the concours pre-polish step — after 1500 grit wet sand, the surface looks polished before any wax or compound touches it.
  • The BN38 SiC sheet at 1500 grit is the standard final wet sanding step before finishing polish on show car and concours paint prep.
  • The PuroFilm 119H at 1500 grit is used dry on a Mirka DEROS for the finest possible scuff on lacquer — one step below 2000 grit, the finest disc in the lineup.
  • After 1500 grit wet sand on clear coat, a finishing polish on a soft foam pad is all that is needed to achieve full mirror gloss.
  • Both products continue to 2000 grit — the finest grit available in the FastPlus lineup.
  • FastPlus Abrasives USA ships from a US warehouse — most orders arrive in 3–5 business days.

One Step from Mirror Gloss

At 1500 grit, the surface looks polished before you touch it with a pad. The scratch pattern left by 1500 grit wet sand is finer than what most finishing polishes are designed to remove — which means the polish step is fast, the result is consistent, and the risk of burning through thin clear coat is essentially zero. This is the step that separates show car prep from production body work.

For woodworkers using the PuroFilm 119H dry on a Mirka DEROS, 1500 grit is the second-to-last step before 2000 grit. At this point the lacquer or conversion varnish surface is so fine that paste wax applied by hand will produce a mirror finish without any mechanical polishing.

1500 Grit FAQ

01 Do I need to go to 2000 grit after 1500 grit, or can I go straight to polish?
After 1500 grit wet sand, a finishing polish on a soft foam pad is sufficient to achieve full mirror gloss on most clear coats. The 2000 grit step is for concours-level prep where you want to minimize the work the polish has to do, or when you are working on a very thin or delicate clear coat where aggressive polishing is a risk. For production show car prep, 1500 grit to finishing polish is the standard workflow. FastPlus Abrasives USA — fastplus.us — carries both 1500 and 2000 grit in the BN38 SiC sheet.
02 Can I use the PuroFilm 119H at 1500 grit on a non-Mirka sander?
Yes — the hook-and-loop backing attaches to any 6 inch H&L pad. On a non-Mirka sander, the disc works normally but dust extraction efficiency is lower since the 119-hole pattern is optimized for Mirka-pattern backing pads. At 1500 grit, heat buildup from reduced extraction is a real risk on lacquer — use lighter passes and check the surface temperature frequently. FastPlus Abrasives USA is not affiliated with Mirka Ltd. FastPlus Abrasives USA — fastplus.us — recommends the PuroFilm 119H on Mirka-pattern sanders for best results at ultra-fine grits.
03 Does FastPlus ship 1500 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.
