I have found a solution to a problem I had with my G-grail, my Medicom '62 Goji.The problem was that the velcro wouldn't stay put on the underside of the dorsal fin strip, which allowed it to gap annoyingly. The solution(appropriately) was Gorilla Glue. I put tacks of the stuff on the spots where the velcro(a more robust replacement for the supplied piece)contacts the vinyl, clamped it down for a few hours, and no more gaps. He has presented problems, my Goji, but now they are behind him(come to think of it, that's where they've been all along). I swear, if I'd had this figure when I was 8 I'd have slept with it...PS
