An interesting question. Maybe Teres will offer up some info.
I think that Teres uses a mix of oil and poly as the finish. I don't think the o-ring would wear it off, but it may cause a track to become visible after a while. There is not much pressure on the platter from the mylar belts so I wouldn't expect there to be much from this drive. Although it would be concentrated at on spot and not distributed around the edge as with the belts. The cocobolo is really hard, it machines nicely and can be threaded.
I wonder what a little wax around the edge would do?
