I used Gorilla Super Glue on mine with no problems. The Gorilla brands tends to stay a little bit more flexible than others. Just apply the glue to the dread sockets of your mask instead of the end of the dread.
Cynoacrylate is just the chemical name for "super glue", found at every hardware store. Though, hobby shops will have it in 3 different thickness'. I always get the medium 'gap filling' one. Have used it to dread many a Predator mask.
