As I was on the motorway today, I heard a bang. It's that type of noise you know something just bounced off the windscreen. As a result I now have three little scratch type marks just above your field of vision as your driving. Does anyone know how you can make them appear less of a mark or remove? The wipers seem to pass over them ok but they are gonna annoy the [email protected]£t outta me? Is there a polish you can get for it?
