Paging the visor-isti ...... The windshield on the Majesty is a rather nice thing to have for weather protection and general comfort but over the years it has aquired many very fine scratches which tend to make it a tad hard to see through in direct sunlight. I presume that the plastic is similar (lexan ?) to that used for helmet visors. Is there a way of polishing these out or is it best left alone ?
