Me too on the OCD thing, but if you actually drive them, you can choose between 1) spend $2-3k on good PPF (paint protection film) and every 10 years redo it, or 2) spend $2-3k every 10 years on a partial repaint of affected panels. Personally, in *most* cases I prefer option 1 because then I feel I can drive it without nearly as much worry, it keeps the paint looking perfect for that entire 10 years, and it's easier to keep clean. Plus you get to keep your original factory paint (if that is important to you.) No wrong approach, just different considerations.
