Morgan, I don't know anybody who has done this, but I remember discussion about this from years ago on the "stickbow.com" forum.
The general idea I remember was just that......the skin is tough and stiff enough, but gar scales are large, thick, and bony, and are partially imbedded in the skin itself making them very hard to remove. I'm sure there is a way, but how to, without damaging the skin itself, I don't know.
