I screwed up. Right. Got that out of the way. The weather looked ok when I started glossing exterior woodframes, but the wind picked up and blew small bits of crud onto the fresh paint ... and then there was a minute of light rain. All just enough to mess things up before I got it covered. Won't do that again!!! But what's the best way to deal with the imperfections? Wait till the paint us fully cured and then sand back, or something else?
