Ideally you would take it fully apart, lightly use ARO on each inner piece and seal in separate air lock bags. Then place each bag in in a foam lined container.

What I really do:
Take the back plate off, put a few drops of ARO on the bearings, and crank pin. Turn it back a forth a few times to hopefully cover the rest of the bearings.
Replace the back plate and use the "dust cap" seals to plug the exhaust port and fuel inlet.
Chuck engine in a box.
