I'm helping a friend turn his wrecked Katana into a bobber and ran into a problem today. We shaved down his seat today and started to put the cover back on it. I originally started stapling it back on using a hand staple gun, with 6mm staples. The problem was most staples wouldn't go all the way through the plastic, or would hit the plastic and angle down so they wouldn't go all the way through. We figured it was do to a lack of power from the gun, so we ran out and got an electric one. Tried that, and ran into the same problem. Before we randomly start trying other methods I wanted to see what you guys do that works. We don't have access to an air compressor for pneumatics so that option is out. Should we be using different staples, a certain technique, a more powerful electric gun, or rent a gorilla to smash them in with his knuckles?
