In talking to Guy at Polaris Inflatables, he said he had poor results with Clifton. He uses 2402; and while I realize that his report is a single data point, but you have to take info where you can get it
With 2402 nearly unavailable here, and the dicey report on the Clifton, I went with the Weaver glue. Seems to have worked well (I am currently only doing little stuff, rather than large jobs, if that makes any difference.) Another advantage of Weaver is that an Inflatable repair shop about 15 miles away carries it, and uses quite a bit, so the stock is fresh.
