Please? Dust and particles in base coat

Please!!!! Whats the best method to remove any particles in a base coat before top coating. "ChromaBase". I think I"m pulling the filter fibers through el' cheapo furnace filters on the intake side of my booth. I"m using a Gray Scotch brite pad and wondering if I'd be better off very easly dry sanding the area with 600 to remove the nubb's...Thanks for any help, I'm right in the middle of it, Walt

Do I need to recoat if there's enough material to hold the color after sanding? I got it looking fairly good. Trying to save another step if possible..Thanks, Filters are history... Walt

You must recoat base anytime you sand it.

Actually, DuPont says not to sand it but remove it and start over
if their base isn't cleared within 24 hrs.
It's in their tech sheets.

Here's what I'm doing. I build giant scale R/C aircraft for professional pilots that compete all across the country. The pieces shown are Epoxy resin fiberglass and Butyrate. All pieces will be cleared in 7776S. I"m not a pro painter but I do manage to get by. I appreciate the advise, this is about the only reference I have other than the guys at the paint store that seem to have no answer but buy more paint. Thanks guys , I appreciate your time on this, Walt
ps, this is not as critical as what most would do with automotive paints. I'm mainly concern with appearance..
