Joe, any idea how long the paint had to cure before it was soaked in fuel? That might make a difference. I've noticed "fuel-resistant" paint needs at least a week to cure. That being said, when I use Crazy glue, I've only let it set up for a few minutes with no apparent problems (yet). One thing I have noticed though, when you go to re-coat an old cork float, make sure it's completely clean of any old fuel. I use Gumout carb cleaner or lacquer thinner and then let the cork dry out completely before attempting to recoat.
