I have a 2014 Tahoe LS 4x2 with 96,000 miles on it. The exterior paint is black. For some reason, the roof has lost it's shine and is becoming a dull flat black. This is also starting to happen on the hood. It's as almost as if the clear coat is wearing off. It is only happening on these areas. The vehicle has been mostly garage kept and not exposed to any environmental causes (chemicals). Has anyone else experienced this? How to fix it? Cause? Thanks for the help.
