The new vans, and cars such as the Lumina van, Silhouette van, and Saturn cars use plastic body panels that come already painted from the factory. They get scratched, and there is basically nothing that could be done about it (not that I'm aware of), since it is already made to be that color from the factory without any painting. I know somebody that has a Saturn, and he said that he has a lifetime warranty from the company everytime he wants to have it washed. If he goes through a regular car wash, the brushes will scuff it up. The dealer hand washes it for him every month.
