I also like to burnish burnish the bow, and use the melted wax, or mineral oil when I when I want it to have a flat finish. If I want the bow to shine I like using waterbased glossy polyurethane (Varathane ) applied with a sponge brush in thin coats, with a light sanding with 600gr. between coats. I like using the poly over mineral oil, as it makes everything a touch darker.
