Hi Snit —
I have a lovely osage selfbow made by our own Clay Hayes that’s finished with hand-rubbed tongue oil. It seems bombproof: repels water like wax and otherwise protects the wood without giving it a shiny appearance. Yet it’s a smooth, hard finish. Hang in and others with more oil experience should be along to offer their advice. I’ve made lots of wood bows but never used oil, but much prefer it based on Clay’s bow, to any spray- or paint-on commercial finish I’ve tried. Dave P.
