It's pretty durable stuff, but repeated use of the rubber pad will cause some wear in the area over time. Hitting it with a coat of varnish periodically should keep it in good shape for a longtime. On the other hand, it's easy to just get a stringer with a pocket on each end.
I wouldn't recommend barge cement for skins. It's a contact cement, and you can't adjust/move the skin while applying it to the limbs.
Most folks use Titebond II or III. First, mask off all parts of the limb you don't want glue. Lightly sand the limb back with a sanding block and about 100 grit sandpaper, then size them with the glue. Wet the skin so it becomes pliable, dab it off so it is just damp, apply glue to the inside, spread it out evenly and position the skin on the limb. Might want to cut the skins close to the appropriate width and length before gluing. Press out any bubbles and let it dry. Trim the edges with a sanding block when dry. Remove the scales with masking tape and your fingernail, working from front to back of the skin. Finish with the material of your choice.
