Here is another glue that has worked well. (I have a feeling it's similar to the Formula 560). Great advise above about preparation before gluing. After sitting on the shelf between uses, this glue needs to be stirred/mixed real well or your first bead will be like milk and just as useless for adhesion!
It applies white and dries clear. The first time I used it and saw the white mess I made, I figured if it did NOT dry clear as stated...I was in deep "do-do"!
