And Wolfgang's come with bare maple on their fret boards thus requiring lots of lemon oil every string change.
Everyone one will have a differing opinion on how to finish a maple board and entirely up to what you prefer. From those shots it was hard to tell if there is any shine yet? Same polishing method for the body to be done on the neck and on my J Bass where I finished the maple board, also used micro mesh and car polish to bring up the shine on all surfaces. Just need to be a bit more delicate on the fret board and not too aggressive with the frets either.
