Sharpie comes off pretty easily with alcohol. I think I'm gonna pick up one of the large tip ones, jam the tip in the grooves then wipe the surface with a paper towel that has enough alcohol to wipe it away but not drip in the grooves.
Please post some pics of the end product, I am interested to see how that works out.
