I have a 1999 FLHTC. The inner fairing has a crack at the center ferrel for the windshield screw.It won't hold the ferrel so I can tighted the screw, even with one of the oversize replacements. Anybody know what I can use to repair the crack so it will hold a replacement ferrel? I used a repair kit for motorcycle body work on my Interstate, but that was 25 years ago. It worked fine, but I don't remember the name. It was in a yellow box and I think it had small pieces of cloth and a liquid...sort of like fiberglass...but I'm not sure.
