Really? Wow... It states right on the front and back of the bottle that it is for PVC and Hypalon. Well that must have sucked. It would be interesting to hear from other owners of PVC boats that use or don't use this product. I use it on my Hypalon boat and like you mentioned, it works great. You mentioned the boat was 15 years old or so, wonder if that had anything to do with it?
