Prine, sorry to maybe be telling you something that you already know, but don't take your car out in the wet or humid weather with only primer on it. That stuff is hygroscopic as hell! It absorbs water and holds it against the metal even longer than the bare metal would stay wet. I speak from sad experience!
I was wondering, what grit of sanding disks did you use in your D/A to remove the paint?
