OK, every time my 2015 JCW is wet or in a humid environment there is an outline of what might have been a sticker on the windshield just off center and to the left (LHD). It disappears in dry conditions. I have washed the windshield numerous times outside & inside, only for the outline to reappear in the right temperatures & humidity. It's about 8" long x 4" wide. Could this have been a sticker on the inside of the windshield with the dock of shipment on it or some such thing? I'm thinking it must have been on the inside....totally baffling I can't get rid of it.
