Tom I just bought two bottles of Tapadera's N-35 nad N-35B stock stain. They claimed it would stain a stock even through tru-oil. I tried the reddish brown on a stock that was finished with tru-oil but was real light. It worked like a charm. It's an alcohol based wipe on wipe off stain. $10 a bottle. They sell a brown and a reddish brown. I'm really happy with it so far. http://www.tapaderaswinchesters.com/stain.html Good luck.
