I have minimal grey. No issues with the paint. A few months back while entering a shopping mall parking area, the yellow bar that is used to stop cars to pay paking charge fell on the car's roof and the rear windscreen. I could see the yellow paint in several places. I cleaned them all with soft cotton and nail polish remover, and inspite such a bad impact the paint remained intact. And, I didn't go for 3M or any other paint protection technologies.
