I've never noticed epoxy primer in a rattle can. Have I just never looked hard enough for it or just not stumbled across it? It seems when most people do body work they usually always spray(hvlp) epoxy primer. It's supposed to be the best rust fighting layer on your car? So is there a reason if they don't rattle can it then why? Or have I just been in my cave to long. You would think it would come in handy for small jobs and such. Thanks, Jay
