Don’t use actual lemon oil, it’ll dry the fretboard out. Use linseed oil or something that’s commercially produced for guitar fretboards. Although if you have something labeled “lemon oil”, there’s a good chance it’s just linseed oil with a lemon scent
I like the crackling in the paint finish, but that fretboard needs a bit of love. Give it a clean up and some lemon oil
