There are two things you need to check. First, make sure you have the right adhesive. There are two seperate adhesives for PVC and Hypalon. Avon is Hypalon so you need to make sure you have the right one. Second you need to thoroughly scrub the area with acetone. If you have used any type of treatment on the boat previously such as a silicone treatment you may have a tough time getting anything to stick.
