I applied thinned Minwax Spar Urethane to a couple hundred square feet of outside trim (verticle grain doug fir) yesterday. First coat was thinned 50-50 with mineral spirits and curred hard. Second coat was thinned 2 parts poly to 1 part mineral spirits.

Second coat was applied late in the day. Unfortunately even though it was covered with plastic, condensation formed and the finish clouded.

What the heck do I do now? Strip the finish off? Try to apply new poly and hope it re-emulsifies?

Thanks guys!
