I'm working on a solid Bubinga neck. Twice now I've tried sanding it to a finished state, and twice it's gotten rough again by the next day. Last night I was very careful to go through all the grits, from 100 all the way through 12,000 (with micro mesh). It was as smooth as glass. Then this morning, not so much. I'm guessing this is the grain raising in places I have runout. Has this ever happened to anyone else? And...what would you do? I was hoping to have an unfinished neck, but now I'm thinking a little TruOil or something. I don't know.
