What do you mean that you did a paint correction? Are you saying you did touch ups to nicks and scratches or things of that nature? I also have a 2007 300, and it has some nicks and scratches (from the previous owner). All the options I've looked into for getting them fixed were super expensive; paint shops saying to fix a nick or scratch in the door would require repainting the entire door and pretty much the whole side of the car to match! If you have any suggestions I'd love to hear it - thanks!
