Pacer Formula 560 canopy glue. It looks like white elmers glue. Goes on white and dries clear. And it sticks to anything! I just used it to glue the canopy on my FuntanaS 90 last week. I used one of my wifes little tools she uses to shape her nails (can't remember what it's called but its like fine sandpaper on a stick) and roughened the the inside of the canopy and the covering where they mate. Works great and won't come apart. Good luck!
