I know we all learn things the hard way sometimes, but if you think about what you are doing, you can usually see the pitfalls. Coating over anything is only as good as what you are coating over. When you paint over peeling paint, what would make one think that the paint underneath won't continue to peel, taking the new paint with it. Same goes here.
This won't be a cheap fix, TJ, but not a total disaster either.
In another thread I mentioned that a friend who had an old Kreem liner fail with the new E10 gas found, after trying everything, that MEK would remove it. You need to be careful with your paint, but probably worth a try. You'll need patience for sure. It may very well strip out your old coating as well. They you can find the problems and fix them right. Might mean a repaint, though.
