Icetail is made of a blend of technora and polyester. The technora doesn't melt. At around 800*F it goes straight to char, as you may have noticed.
You will have to use tape, glue, epoxy, heat tubing, or my favorite, a proper sailmakers whipping. Here's a half-decent step by step I made a while ago. I think one of them is wrong so if you're doing it and find a prob, let me know and I'll fix it!http://goo.gl/EizfM
ps- once you know how long you want your split tails to be, it's time to splice it!
