What type of oil is used on a rosewood fretboard? I was stripping the finish off a neck yesterday and some of the stripper got on the fretboard. It seemed to pull the oil out discoloring the wood. Also, would there be a problem with oiling the entire neck, maple and rosewood, and then applying a satin finish on the maple afterwards? I want to darken the neck slightly and I thought the oil might woork well for that.
