I take a route parallel to Jim's: traditional "slacum" mix (BL, turps, carnauba wax, venice turpentine for dryer)and rottenstone as a do-all grain filler and cut-down abrasive. There are all sorts of micro-abrasives that will produce a reflective surface. I've used Novus scratch remover in a pinch. My all time favorite: Simichrome metal polish available wherever men are obsessed with acres of chrome. I guess this doesn't sound right but it works. Simichrome-impregnated rag never seems to loose its effectiveness. Similar to the Great Gun Oil Question. You can buy a lot of special purpose gun oils for 5-6$ the squirt or buy a quart of Mobil 1 20w50 racing oil for the same 6$ and be set for life.
