So me and my buddies got a snapper that was HUGE tonight. I kept the top half of the shell (a little bigger than an oversized tennis racket). The neck on this thing was the size of my forearm halfway up...heck his wrists were nearly as big as mine!

That inside of it looks like plain bone and wont need any treatment. The outside is a little more like a leather coating. (no it wasn't a softback).

Will that outside covering dry up and harden on its own or is there anything I need to do to it?
