I have the Thule H2Go kayak saddles, which I really love, but one by one the gray pads that support the boat are giving it up, splitting on the underside of the pad where the support pin goes through. What can I use to repair them? I figure I can put some kind of tough fabric over the split area, with some kind of miracle space-age glue to hold the fabric in place; whitewater raft repair fabric comes to mind, but I'm at a loss as to what glue to use. Any ideas? Thanks in advbance, Greg.
