I just recently purchased a Warmoth J-bass maple neck w/rosewood fingerboard. The neck is basically unfinished. What I would like to do is put some kind of underlying finish on the face, and then paint the face black to match the body I'm using it with. The reason for the underlying finish is make it easier(in the future) to take the black paint off when/if I want to use the same neck on a body that is stained or a different color. I would be using a heat gun to strip it. My question is -What would I use for that underlying first coat finish?
