No I have a few hour set back, and I don't know why the paint is so screwed up....It was Krylon, and I'm not buying more of it.
I would think it's too late to help you, but the checking is likely due to contamination OR incompatible paint. Don't know what to do besides primer it before the paint fo rincompatibility, but you may want to sand, then wipe everything down with laquer thinner, or alcohol to make sure there isn't any contamination.
