John E. Traister has 2 books, published by TAB Books Inc. One is titled "Professional Care & Finising of Gun Metal" & the other is "Professional Care & Finishing of Gunstocks", a lot of elementory information, but if you don't know it , it's good information. Don't know if they're still in print, I got mine in a used book store,( 1 of the perks of livin in the big city )but I'm sure Amazon or 1 of the used book sellers can hook you up. Good Luck, ...MIKE...
