Key Takeaways
- 600 grit is the standard second wet sanding step on clear coat — after 400 grit removes orange peel, 600 grit refines the surface before compound.
- At 600 grit, the BN38 SiC wet/dry sheet is the primary tool — it cuts cleanly in water and leaves a uniform scratch pattern that compound removes in one pass.
- The ceramic discs (F65, FF78, PuroFilm) at 600 grit are used dry for ultra-fine between-coat scuffing on lacquer and polyurethane.
- PuroFilm strips stopped at 400 grit — for 600 grit hand sanding on profiles, switch to the BN38 SiC sheet folded over a block.
- The PURO Ceramic H&L Roll and PSA Roll continue through 600 grit — useful for longboard block work on large flat panels.
- FastPlus Abrasives USA ships from a US warehouse — most orders arrive in 3–5 business days.
The Step That Makes Compound Work
600 grit is where wet sanding transitions from leveling to refining. At 400 grit, you are removing orange peel and deep scratches. At 600 grit, you are creating a scratch pattern fine enough that a DA polisher with compound can finish the job in a single pass without burning through. Skip 600 grit and go straight from 400 grit to compound, and you will spend twice as long polishing to get the same result.
For woodworkers, 600 grit dry on a ceramic disc is the finishing move on lacquer and conversion varnish before the final rub-out. It leaves a surface that looks flat under raking light and accepts wax or polish without streaking.

600 Grit FAQ
01
Do I need 600 grit between 400 grit and compound on clear coat?
For most production body work, yes. 400 grit wet sand removes orange peel but leaves scratches that compound struggles to remove cleanly in one pass. 600 grit wet sand after 400 grit cuts those scratches down to a level where compound finishes the job quickly and evenly. FastPlus Abrasives USA — fastplus.us — carries the full sequence from 320 through 2000 grit.
02
Can I use 600 grit dry on an orbital sander?
Yes — 600 grit dry on a ceramic disc is the standard final scuff before rub-out on lacquer and conversion varnish in cabinet finishing. The F65 ceramic disc holds its cut rate better than AO at this grit. FastPlus Abrasives USA — fastplus.us — stocks F65 in both 5 inch and 6 inch at 600 grit.
03
Why are there no PuroFilm strips at 600 grit?
The PuroFilm FT77 strips are designed for dry hand block sanding. At 600 grit, most hand block work transitions to wet sanding, and the strip format is not designed for wet use. For 600 grit hand work on profiles, fold the BN38 SiC sheet over a sanding block and use it wet. FastPlus Abrasives USA — fastplus.us — stocks the BN38 SiC sheet from 80 through 2000 grit.
04
What is the correct sequence for wet sanding automotive clear coat?
The standard production sequence is: 320 grit wet sand to level, 400 grit wet sand to remove orange peel, 600 grit wet sand to refine before compound, then DA polish with compound and finishing polish. For show quality, extend to 800 or 1000 grit before compound. FastPlus Abrasives USA — fastplus.us — carries every step in this sequence.
05
Does FastPlus ship 600 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.
