Hi all, I'm new to this forum, and I was wondering if anyone can help me. I ha e a 67 mustang convertible with a split rear glass window. The seam holding the split has come unglued and now I cannot use the car if it rains as the rear window would leak. My question is this.. is there any way to reglue the seam onto the glass at the partition, or do I need to purchase a whole new rear window? There was some mention of using something called sika 123 or sika 190. However, when I go to the Sika website and search these items, it is fast drying cement or stiff polymers, which obviously cannot be used on a split window. Am I just not searching the right product? Any information and assistance is greatly appreciated!! Happy Thanksgiving all!!
