Ok...so my DA came with worn and coming off the arms wiper blades...these I have of course replaced but the windshield is damaged...it has slight scratches pretty much the entire wiper range and is ok until it gets dark and then street lights and headlights put like a 1000 glares in my face, its horrible. Are there any options aside from having the windshield replaced? Wax, some sort of glass filler? Thanks all
