As a turner, I can verify Derek's suggestion of the Shellawax... I use it on every plane in my collection. I happen to have an additional benefit, however, in that I have an advanced buffing system that runs on my lathe, and makes the Shellawax look simply marvelous as well as adding a slick but not slippery surface so your feel of the wood on your plane is like no other. Everyone I know that uses it raves,,,
