I have a 2010 MCS hardtop I just bought used last week. I am starting to slowly detail different areas. I was putting Mcquires Ultimate on some faded trim parts and notice that the rubber seal between the windshield and apron covers is starting to disintegrate. I looked on line and it seems this gasket can be purchased separately. Can anyone confirm this and if it is glued to the apron covers or if it is just a pressure fit? Is is difficult to DIY?
