When I was a kid I remember you could tell which cars were starting to get old by how faded the paint was. There were some cars that were never parked in the shade and the hoods and trunks were very sun bleached compared to the sides. The really bad ones would have big curly flakes of paint peeling right off. I guess they figured out what was going on because it doesn’t seem like a big deal anymore. Cars stay bright and shiny a lot longer.
