Hi, I lately noticed scratches on my Model 3 windshield. They are very fine hair like scratches and could be seen at night or during bright, cloudless days with the sun. It is clear that all scratches ran tangential to the path of the windshield wipers. Have you noticed this on yours? Any thought. * Jun 2018 delivery. Going to Petro Canada touchless SuperWash twice a week since beginning of the Winter. Could wiper rubbers become hard because any of Triple-foam cleanser / Body Gloss wax / Clear coat protector cycle wash?
