so I had a fairly large project with 4 large pieces some shelves backs and doors.. I have a small shop and after getting a third of the way through finishing it I took it to a shop to have it sprayed with lacquer. I should have checked it better before bringing it home but she had done kitchens for me and no problem. there was quite a bit of shop dust on it but when I dusted it off it was rough. Can I sand this off with say 3000 grit sand paper or? Sure could use some help
