Paint help quick

Garage temp is 70f. About 10-15 outside. Wife is loving it. Car is covered so I don't get a big temp drop when garage door is opened. And the family knows door opens, get out and get it closed ASAP. Only opens about twice a day and not at all when I was painting.

I didn't think I had much to lose, so lightly sanded the spots down, cleaned everything again primed and resprayed it. Came out good. Not a Montery Bay showpiece but much better than it was. Not sure why those spots lifted, guessing even with all my efforts to clean I got/left some contamination there?
