My 30 yr old NRS sprite is made of epdm rubber. After a lot of abuse it still holds air however I need wear patches at the "4 corners". I know that this epdm coating is bottom of the line as compared to other synthetic rubber compounds such as neoprene and hypalon. What is the best adhesive to use for applying the wear patches and the other inch long rips and tears I've picked up over the years. Is there something better than Clifton, Shore, and Stabond???
