Thank you for the reply. I'm baffled about it too. I does not appear to be the clear coat peeling, it appears the carbon fiber is a type of "wrap" that is bubbling. The way it looks, it looks like I need to peel all that crap off, not sand it. But I'm not sure what is under it so I don't want to open a can of worms. I have to worry about the roof leaking too. Hoping someone that is familiar with these roofs will see this post.
