Let me guess-it sits outside in the sun a lot? My 2011 started developing the "spider web" paint defects after a year or two, likely caused by UV.
It is not possible to remove them without extreme buffing if at all. I was at Jackson Center when Airstream tried that who told me the manufacturer advised them to buff them out. They buffed it right down to the black rubber and then asked me what I wanted to do. I said give me the parts to replace them all, and I'll do it myself because it would take about three days for them to do so. They were more than happy to do that to get rid of me, as I'd been there a full week already.
I'd say if they won't replace them, having them repainted is the only cure.
