probably not
I have had the identical problem as many, many inflatable owners have had lately.I too though that my dingy was hypalon but the store where I bought my adhesive/glue for the repair assured me that there are very few recreational dingys made of hypalon. Most if not all are made by Zodiac and labled with the store brand. Also nearly all are made of a type of high grad durable PVC. I was amazed to find that PVC was the material since I associate this stuff with water toys and other such flimsy products.He assured me that this type of PVC is very durable and will provide as good a service under medium duty conditons as Hypalon. He said that a comparable Hypalon dingy of the size of mine (9 ft) would be thousands more than I paid for the PVC dingy.Finally; go to a marine supply store and get the two part adhesive. It runs about $30 a kit and works great. It is not an epoxy. The second part is an additive which makes the adhesive resist petrolium, farm chemicals and other aggressive chemicals found in water today. You need not mix the entire batch, unless the separation is so large you need it all, simply eye-ball the mix and save the rest for later.When doing the fix fully deflate the dingy, clean the area to be repaired with MEK, apply the glue, set some sort of very heavy object on the area and let it sit a full 24 hours.I had about an 8 inch section to re-glue last spring and it doesn't leak any more. I fully expect, however, for it to separate somewhere else one day. There have been articles written in the boating mags concerning this problem. I wonder if Boat US is planning to get on the manufacturers about this issue.Good luck,Mike
