I wanted to get a nice, reasonably glossy finish on the cocobolo without using oil. After some research on the interwebs, I found this.
On the left is "EEE Ultra Shine." It's an abrasive wax that puts a finish on bare wood - it says 'For Turners and Restorers.' And on the right is Shellawax. Both are made in Australia. I have seen some pictures on the interwebs of some nice pieces finished with these products, so it seems like it's worth a shot.
I didn't put anything on the bottom surface - that will be glued to the guitar top.
The bridge is not perfect, but it looks reasonably good. I'd actually like another shot at making one, but I don't have any more blanks and I want to finish the guitar!
