Not knowing what was used, I'd guess you need to find some acrylic lacquer primer. You can almost prime a rusty bucket successfully with that stuff, and once it has been applied, you can over coat it with epoxy primer if needed. Advantage is a good brand. Mix it 1:1 with a decent grade lacquer thinner and coat everything you can. I've heard those same horror stories, and most of them come from people living in humid areas or areas where it tends to rain a lot. But you hear a lot of things. Good luck.
