I should know the answer to this, but some things puzzle me about this: I'm currently doing my first neck refinish for a build I'm doing. I bought a neck with a rosewood board for a vintage build. I hated the orange finish once it arrived, so I hand sanded all of the heavy lacquered finish to the bare maple, and mixed a stain that turned out great. I did stain the sides of the fretboard and the piece above the nut that joins the headstock face. I applied polyurethane to all of that which Fender does too. The fretboard is nice, but the stained sides are beautiful and I really wish I could carry that on to the fretboard. Here's what I "THINK" I know: You do NOT want to seal the rosewood board with poly, you need to leave the grain open to breathe. And I believe that staining without poly means that it would rub off, and likely the F1 oil I condition with would take it off as well. If this is all correct, 2 things bug me: 1. People use India Ink to "ebonize" rosewood for a vintage look. Does that not rub off? 2. My brother (RIP) had a beautiful Rickenbacher that had a rosewood board that had a thick gloss finish on the rosewood board from the factory. Why was that not an issue? Any input is appreciated. I know that when I start conditioning this new board it will get darker and richer, but I did want to explore my questions about stain and rosewood.
