well i tryed powdered graphite on my megaminx and it seemed to work really well, especially for breaking it in. But it is more abrasive because it is a powder, so i dont know how it wil affect it in the long run. And lanocote is used in the sailing world, its made from sheep fur and its oils. My mom lived on a boat for some years and she suggested it. The only problem is that im landlocked in colorado, so its not easy or cheap to get ahold of.
