Thanks for the replies!
Susanne: I saw Fret Doctor wayyyy early on in my searching. I seem to have forgotten a lot about it. I will have to take another look.
Ken: I was wondering about the durability of lacquer. I have seen it mentioned as an overcoat to shellac, but not much about fretboard applications.
Things are looking up. My project arrives tomorrow afternoon.
I plan on before and after pictures. Unless I screw the whole thing up, in which case I'll burn them and pretend I was never here.
