ok dude, heres the deal, or whats up... chevy, ford, chrysler, and toyota all had this problem, the paint not sticking to the factory sealer.... so, you are going to have to strip the factory paint down to metal, with say 80 grit on a DA sander, or air craft stripper and remove all the factory stuff, and including the work you did, and start over, unfortunatly, the rest of the truck is headed in that same direction if it has all the factory paint on it too.....
