I like shellacked bar tape, but it does limit your use of many modern gloves with a fabric-type palm as they can be quite slippery….That sort of negates the purpose of the bar tape…right? Leather and fake leather gloves seem to be fine, in my experience. Shellac is also very forgiving so as your shellac gets a little worn, you can always touch it up with another coat as the new shellac will solve the old and form a nice new coating. At some point we should have a discussion about another cycling related use for shellac…and one almost forgotten. That is the shellacking of tubular tires as a substitute for cement to fix the tire to the rim. It was primarily used for track tires, but also sometimes for time trial tires.
