I'm reading right from Track of the Wolf, no heat, no lengthly days cold browning, 4-6 coats 3 hours apart and your done. That doesn't sound like a rusting process, so it says on page 415 catalog # 17, Sounds almost too easy! When I heated the 54 barrel with a rose tip torch I then used tight woven white cloth and even coated the metal surfaces with the nitric acid getting an immediate browning color, After the acid browning I submerged the parts in oil to cool down and protect the new metal surfaces from further acid attack. and it all worked well maybe not to OSHA's specs but It worked. It gave a rather unique antique brown finish for the Hawken which was just what I wanted. I like LMF antique wood stains work well and can be custom mixed to make that 1 perfect color, and I think they are more concentrated and giving greather depth infusion and color. I like to mix cherry, Lancaster maple together works well after aquafortus (nitric acid, used on the bare stock to heighten the stripes in the soft tissues of the maple stock. Turns the stock yellow the using a propane torch start slowing heating the stock front to rear until the whole thing turns black. Then hit the stock with water an baking soda water solution to neutralize the acid then let dry and begin your sanding and watch the figure jump right out of the stock. It's work but man do you have some nice stripe and figure present.
