I have a Wood River V-boat, (Summer Breeze model), that has a pin hole leak in it. I've patched the bladder in the past with a patch kit and it's held fine. The tube of glue I used to patch it had dried out since the last time I used it so I threw it away thinking I'd have no problem getting it replaced. However, every patch kit I've found has been made for rubberized material, and my float tube bladder is made of thick vinyl. The glue just stays gummy and doesn't dry and bond the patch properly. I'd like some suggestions.
