My last project, I used the waxed paper taped to a 3/8" piece of polystyrene foam with a 1/4" wood backing piece on each side of the patch, then clamped it. The foam/wood was so I wouldn't leave clamp marks on the buttstock, and the foam distributed the clamping force fairly equally over the irregular surface. Worked out OK. There were a couple voids & bubbles that had to be filled in after initial sanding, but I was happy with the join.
