I agree with Seth, unfortunately, I didn't take his advisement closely enough.
For all those that are about to paint their armor too...use only a thin coat of paint or you will regret it!
I used Krylon plastic paint thinking it wouldn't do the same, guess again.
I just srewed up my armor and I did wait a few a few days before adding my second coat and/or gloss enamel coat. (after screwing up with the paint, I used an enamel on another piece, samething happened) I don't think it's the time duration because the paint is"supposed" to be dry in fifteen minutes. It's definitely the amount you spray. The portion of armor that I added a thick coat of paint or enamel gloss is where the paint "bubble up" and the thin coated portion of the armor had no problems.
Good luck all, I'll be sanding down my paint for the rest of the day. <_<
