Apologies. I think I posted in wrong section before: Hi. Can anyone recommend a shop which can strongly buff out light/medium scratches and effects of years of acid rain on the side windows and rear windscreen my beloved E38 ? Regular detailers can't seem to do it and even when they buff, the glass still shows visible scratches and feels rough to the touch! The windows are double glazed and would cost a bomb to replace, hence my ask. Thanks in advance !!
