What Fabric is the tube? I work with Hypalon, but the process is the same AFAIK
5m isnt massive so you and one mate could do it easy, or on your jack jones but its easier with a hand.
Do it all in one hit, glue everything wait a bit then get sticking, trim the ends off if needed, then Roll the living daylights out of it, i mean once you think youve rolled it enough roll it some more and youll be just fine.
Then later on or the next day clean it all up and your done.
fresh blade for trimming the ends off the rubbing strake, nothing worse than trying to chop through with a knife as sharp as a spoon
