POR-15 horror.

Someone applied it to my 68 Barracuda after they installed new floorpans. It did not stick!! I took a blower and the sh*t blew right off. That is where the new pans were installed. Looks like they scuffed the new steel but did not acid etch it! ALWAYS acid etch first!! Of course that is after you clean thoroughly! It did stick everywhere else that it was applied. Now I have to grind most of it off and reapply. Por-`5 works good when applied properly. Good luck!
