It's watercolor over *bare wood then CA. Actually I have found a cheat. My watercolor use to run with the grain of the wood, now I apply a bit of *eggshell color latex wall paint (Over the holly) with a paper towel (lathe running) and sand it lightly then apply the watercolor. The latex seals the wood without changing the color.
Can't do a trade, sorry. I made the pen for a real estate client that is into wine making.
