Reaper for glassing formers to a glass fuse I would reccomend the 20 min or better yet the 30 minute epoxy. you want it to cure slow and be able to adjust if necessary. if you use the 5 minute you dont have much time to wet the strips and lay them in the fuse. I never used any slower than 20 minutes when working with epoxy. as for the formers you can tack them in place with a little hot glue then they will stay in place so you dont need the epoxy to cure fast. same thing when glassing with it use something like 30 min epoxy to give you plenty of time to work. especially if it is your first time using it to glass.
