I use my own old-time mixture from my gramps (violin maker) containing linseed, carnauba wax, Japan dryer, a couple of other items, put on warm, exceedingly thin coats, once per week, over 8 weeks. Hand rubbed after each application. Appearance is as glass with a soft sheen and all grain filled. Key on old wood is to get it clean first while saving the character of 100 plus years. On a vintage arm I do not want a refinished or new look.
