I've used a super small amount like one drop between all finger tips of each glove, olive oil. Such a small amount that not much transfer happens to buds noticed no sign on buds and they seemed to make the gloves last 50% longer which can save $$ especially on a budget. Depends who's using it though I can see people over doing it. Also some people just handle colas too much when trimming. Cocoa butter sounds like the same idea right? baby powder inside gloves seemed to make them last longer too. Not telling ya what to do just my experience
