Huh thats kinda strange. I for some reason pictured a much larger section of plastic peeling in my head. I wouldn't think it's any sort of "paint protection" doing that. When dealerships sell you that it's generally just a coat of wax on the car (which as far as I'm concerned any claims they make about it is completely false). I would try hitting it with a plastic polish before anything. Like I said my personal recommendation would be Meguiar's PlastX, it works great and isn't going to hurt anything. You may have to sit down for a while and really work it in, but I would imagine it would be able to help it if not fix it. One of my head lights kinda had a hazey thing going on at one point, I think it may have just been some clay bar residue on it, but I sat down and rubbed some clear plastic polish in to it for like 15 minutes and it made it look brand new again. Whatever it is it looks fixable from the picture.
