Pete,
Thanks for the explanation. From my point of view it sounds like a great thing to try on my next stock finish. I like to try different things but I am always afraid the color may get in too far and I cannot remove it. I am still afraid to mess around with alcohol stains for that reason but I will get around to it on scrap pretty soon.
Does the tea ammonia combo have a red or green tone to it? Would you use it on a fairly nicely figured stock that seems to have no fiddleback or would you go with a more conventional stain in that case?
