Angry OK fellow Michelangelos, what do you think is going wrong?

Painted the frame and core support of my LeMans in my garage. When running my hand over the dried paint, some spots are super smooth and the finish looks perfect. In other spots, the paint feel like 120 grit sandpaper. I'm thinking a few things might have occurred-

- I didn't apply enough paint
- It dried too quickly
- Overspray settled

When painting, it all appeared to have that thick wet coat as it went down. There was never any indication there might be a problem, except when I came back around for 2nd wet coat, the parts seemed to be almost dry already. ?? I've painted with "lesser" paints, (Rustoleum, Krylon, etc) in a wide range of temperature and humidity, with better results. This Martin Senour paint seems to be much more sensitive to conditions for some reason IMO.

75 degrees
18% humidity

The core support was done many weeks ago, but the same thing happened, twice. The first time I just presumed I didn't put on enough paint, so sanded with 400 and painted it again. Same issue occurred, but not always in the same areas. Conditions similar -

75 degrees
30% humidity

Anyone else run into this? Any idea how to resolve? I don't think its the paint as many have used it with good results. I believe its me or my conditions, just don't know which.

BTW - Pic just reminds me of how much work I've got to do again........it doesnt show anything pertinent to the problem
