Well, look. You see how you've got a lot of white going on there? Every single little fleck of dirt or whatever is going to stand out like a beacon against it. Scratches and dents are even worse. It just looks awful, especially on camera. When you spend as much time in the public eye as I do, you really need to look your best. The red's a lot easier to manage since I don't always have a lot of time to fuss with my paint before I have to meet with delegates or give interviews.
