I was going to say red paint pen until I saw the white script japan and thought maybe a cream would be nice too. For bar tape, I wonder if cloth tape (maybe over something to provide more padding) coated with an appropriate number of coats of the appropriate color shellac would get you what you want. For ideas, the rivendell site, though I'm not saying to buy from them.
