Being strapped for space, I take everything out of the shop, everything to the walls. sweep it and then blow it out with a leaf blower. Then I let it settle and do it again. Repeat as nessesary until I don't stir up any dust w/the blower. Then the car after gettin' the same treatment, goes back in and the place gets the garden hose trreatment. I always spray the final clear coat very early in the morning, before the flies and mosquitos wake up. Always comes out good. I don't paint many cars, so this has to do. I always out of habbit I suppose wet sand and buff the final coat anyway just to get that wet look.

I once (when I didn't have a garage) painted my truck outside. FInal coat was Delclear. I had it all preped and got up real early one moring, wipped the dew off. As soon as I could wipe the body off without the dew coming back, I sprayed it. Came out like glass, no dirt not even on the hood. No one could beleive I shot it outside. Maybe I just got lucky.
