Cabot Australian Timber oil is what I prefer.

| Woodworking tradition is that the underneath not have finish. Just

| useful since it further protects the boards and will reduce and
| expanding and contracting that occurs with all wood. Having said
| that, almost no one would go what is a significant amount of trouble
| to finish a surface that no one ever sees or uses.
