That video is like the 'standard' procedure, using isopropyl alcohol to remove glue residue, should be same for all valves, I have had some success with nylon glue but it is very difficult to use as it makes the material curl up and wrinkle very fast. I sold my Duotone because I was fed up with valve issues, otherwise great wing. Also you could just remove the dump valve and patch over, then deflate will take longer but problem solved!
