“But what if you have a hairy arm, like me?”
Try duct tape. Put it on then yank. If that don’t get it a propane torch will take it right off.

Actually what if I just covered my hairy forearm with duct tape and just left it there - that would make a nice projection screen. Do they make white duct tape with a reflective surface?
