paint sealant is clouding, bubbling and peeling off

There have been a couple of spots where the paint sealer was getting cloudy and bubbling up on the top of the liftback door for over a year. Over the last month, every painted surface that has ANY surface area that has upward exposure has broken out with the same problem, like a pox. I was not terribly concerned to begin with, but this is ridiculous! A new paint job should be offered by GM!
