Ray, lots of good suggestions here. I'll add mine and you can take it for what its worth. After tooling and dyeing (or in my case, sharpieing) I oil the piece up a bit with some quality oil like 60w Valvoline. Today I used HD 60W because I was out of Valvoline. I like the Fiebing's antique also. I used a sandwich bag today,out of gloves.I just dip a couple of fingers in the antique and lightly smear it over the work and into all the impressions.Next I wipe off the excess immediately,I don't give it time to dry. Then I take a rag wrapped around a finger and get some more out of the impressions as I like to use the antique to outline.I then go over the whole thing again with a damp cloth to get any stray stain,let it dry for a day or two, then finish it off with some Aussie Conditioner.
