I'm working on refinishing one of my builds from a few years ago, and I've got a dilemma. When I built the bass, I used Deft nitro. That's not the problem, though. I'm stripping it to refinish, after reworking the whole bass, but I've hit a wall and need some advice. The fretboard is also nitro and needs stripping. Here's the problem. I need to strip the old finish from the fretboard, but I installed fiber optic side markers and any chemical stripper will melt the fibers and ruin the markers. What's my best bet? Can I remove the finish without removing the frets, because that again raises the issue of the fiber optics. I don't want to risk damaging the fiber optics accidentally. What would you guys suggest? Should I carefully paint some Citristrip between the frets?
