Well, I have a pinhole leak at a site on one tube of my Hypalon RIB that was scraped a year or two ago. I can't find the repair kit. I bought one at West Marine that was $62! It contains a 70ml tube of adhesive, a sheet of 100 grit sandpaper, and about 10 round patches of various sizes. Date code on the kit is Oct 15, 2007. I heard that this cement has a shelf life of 18 months. Does anyone know if there is a generic equivalent of this adhesive that is available in local stores, fresh and cheap? Also, where might I find some Hypalon material?It seems like a multiple-day, arduous process to cement a patch the "right way." Any tips for quick field repairs that allow an immediate return to service?Thanks,jv
