OK, thanks for all the input people.

Based on what was said here, and what others have told me today, I think it's because the room I was painting in was too cold (about 60).

Not sure if its the powdercoat because I sprayed onto a powder coat before w/o problems. (different frame, different color, same powdercoat painter, same rattlecan paint on my part.) That one came out fine. Only difference I can think of is that the 1st was done in sept, when the weather was warmer than where I'm working now.

Think I need to re-sand and start over, or should I try spraying over the bad lugs once I get the frame and paint into a warmer area?

And I promise for pics when this is done! The lugs are nice capella lugs (which I'm painting black) and the powdercoat is a metallic sparkle green
