I know I am going to receive a lot of harsh comments regarding this post, but I have no affiliation with the company or its product. Just relating my personal experience. After 12 years, our haplon inflatable was leaking air from many locations, mostly due to abrasion. Not able to obtain the proper repair components, I thought I would try to cover the areas with "Flex Seal liquid". To my surprise, after 2 months of use and temps ranging +/- 50 deg. the repair is holding up and no air leaks in the pontoons. For me this was a cheap and easy fix and seems to work rather well.
