The funny thing is I just had this same thing happen at work a day ago due to the solvent not being totally flashed off (cold temp wasn't part of it though). I will try to remember to take a picture tomorrow of it. For me it wasn't such a pain to take care of, since all I had to do was grab another shell to paint in the place of the two that I had it happen to.
If I were you I would just let it bake for a day, then paint it later the next warm day.
