Looking nice Doc!
I like the body grain... I vote for the clear DingoTone finish! :-)
Re the snail and slug barrier, it's 30mm wide, so as DB was alluding not that much of a bargain if you compare to the 50mm from PBG.
I actually used a combination on my STA1. PBG issued tape for large pieces (bottom of the cavity) and snail and slug tape for the edges as it's close to the depth of the cavity.
Anyway, it's only copper tape... as long as it sticks and is a good conductor it won't change the tone of the guitar.
Enjoy the sanding!
