Hi Rob, love the headstock shape. It almost has a shark's snout look about it at the high E end.
Absolutely no idea what to use on a Maple fret board and will need to deal with this too when I get around to working on a J Bass kit bought recently. From what I have seen and read DT Wax might be the way to go or you can use TO if you want a more permanent sealed and/or shiny look.
One of my mates has a EVH Wolfgang with a maple board and he uses lemon oil which seems to be the go to thing for Rosewood but not so common for maple. It will take me several weeks if not months before I get up to this stage and hope someone comes up with some good ideas for both you and myself.
