I have a Sevylor Fish Hunter inflatable boat which I have had for about a year. It is a really great and easily portable boat for fishing, and I love using it.
I have been planning to build a sectional wooden floorboard for the boat as well as some custom seats and some other enhacements, and because it was a nice day today, I dragged the boat out and inflated it fully, so I could begin working on the plans. However, I soon noticed that there was a small hole in the outer chamber through which air was leaking.
I really need to patch this up and I want it to be the most rock-solid, heavy duty patch possible. I tried a rubber patch and cement intended for a bike tire; it didn’t stick very well, possibly because it was made for rubber and not PVC. I tried a general-purpose “vinyl/rubber/plastic” patch, with included cement; this, also, is not really adhering very strongly.
What is the best way to do this? I would like to patch it up with materials I can buy locally, rather than ordering the official Sevylor repair kit and having to wait for it.
