Scotty, I have a 2012 Ford Fusion. It's only 7 years old and the paint is cracking and peeling off in chunks on the roof! What in the world is going on? I live in Iowa so we deal with lots of rock chips and rust down below but I've never seen anything like this!
That is not an aluminum body. If you have never waxed that car, then the paint finally gave you pay back. The paint is suppose to have a wax layer on the clear coat to protect it from the bad sun rays.
Can you post some photos, Ford was known for having issues with galvanized galvanic corrosion on aluminum body pannels , or it could be something completely different
