On my drop bars I put a strip of cork tape across on the top of the bar extending to each brake lever. Then a piece of cork tape on the flat part of the drops. Then I wrap with cotton bar tape Cateye etc. Then I put 4 coats of shellac on top. Lasts for a very long time (years) and if it starts to wear, put on some more shellac. I usually go with black tape as it matches my bike and hides the dirt.
