When I glued my rattler skins up, I used TB2 and then placed plastic wrap over the skins and then wrapped the limbs with bicycle innertubes. I used a razor blade to trim the excess and then sanded a nice clean line in. Protip: Mix a little water in with the TB2 and lightly swab the wood and skins before applying the rest of your regular-thickness glue. Give the thinned stuff a minute to soak in, it'll help adhesion. Pay very close attention to bubbles under the skins, try and work them out but if some show up after your done curing, poke a small hole with a needle and squirt some of the glue in there. They will usually suck in.
