My 08 Mustang GT and 08 Taurus X, both with aluminum hoods, have paint failing at the leading edge. I don't know of any company that would warranty this on 12 going on 13 year old model cars, let alone with over 130k miles in my case.
Come to think of it, my 67 GTA was at 13 years old when I bought it from the original owner. That looked like it went through the ringer multiple times compared to my 08!
