    I’m working on a 1920’s Regal with an ebonized fingerboard. I’ve seen these referred to as “ebonized pearwood,” but all I know is it’s worn through to a light wood, definitely much softer and grainier than maple. I want to keep the finger wear through the ebonizing, but build up a little layer of protection.

    Boiled linseed oil seems ideal for this. However, I’ve heard boiled linseed oil doesn’t react well with tannins. Tannins may be part of the ebonizing process. Does anyone have experience with oiling/protecting these fingerboards? I may use a furniture oil with beeswax that I’ve had good results with as an alternative.

    You might try tru oil for this. You can actually thin tru oil with naptha/mineral spirits, so you could get it to penetrate. After a cursory glance at the internet, I cant find any mention of a similar issue with tannins.
