I recently purchased this 2011 vette. Love everything about the car, however.... it has this problem on the rear quarter. I took it to a detailer who said its clearly burnt through the clearcoat and needs to be painted. He is affiliated with a paint shop BTW. I am not sure if thats correct. That spot has a slinky smooth waxy type feel to it, while the unaffected areas still have a gritty feel from dirt. Any ideas on how I can determine if its through the clear coat ? I tried chemical guys clean slate and nothing came off.https://www.evernote.com/shard/s284/sh/5988a567-e8bf-4ce9-8f8e-4dac43468899/d4565d66b6f29ff7bccd75867b5989fd
