It occurred to me that hollow pin chains would not be good candidates for waxing since the dried wax would go to waste filling up the hollow pins. But then I also thought that if a hollow pin chain had tiny cross drilled holes that this would be potentially a great way to work more wax into the internals of the chain. AFAIK, no hollow chain has this, but I can't see why a manufacturer could not easily make a chain like this that is wax ready.
