so I was driving and some object hit my windshield. I didn't crack the shield but it left a mark, seems like some kind coating is peeled off. (I was told that new lexus has water repelent coating on window, mine's 07 IS) what would be the best thing to do? take it to window shop and let them fix it? or can i buff it out myself and apply some coating over that area? If so how? I wasn't too happy because I haven't even had 5k service yet. thanks
