Well even though there's not a bit of rust anywhere on the car, and the paint is in very good condition 10 years of being used all season round have caught up with the rims. I'm not sure what those white lines are but they almost feel like some coating that I could pick off with my finger and some sort of solution. I want this to be a DIY project and if it's something that only a professional can fix, then I'm not going to fuss and will just leave it, I guess I just need a new project. Any ideas?
