Had a finishing project go sour last night when I started to spray the clear coat and when I went back to scuff sand, it had a bunch of black specks which were from the rust forming around the lid that I forgot to wipe during a previous project. I figured the 190 micron filters I got would be sufficient, but it appears they aren’t fine enough.
What size do you all use? And where do you get them? I see they have 125 micron on Amazon, but was thinking maybe to go finer. I plan on continuing to use the 190 micron for BIN Primer, but for the enduro white poly and enduro clear poly, I’m looking for something that gives me more piece of mind as I have a ton of work ahead of me now sanding these specks out of the finish.
