Not so Roger, if the unit is on its side water can and will get into the
top bearing, Like most rotors they are only intended to shed water.
Water can also get through the mild steel plate / rotor housing
interface on the bottom. The pot is vulnerable in these circumstances.
If the unit is used on a tiltover tower its worth spacing the rotor off
the plate by a few mm to allow drainage and using a temporary cover to
protect everything when horizontal, a plastic fertilizer bag works well.
And yes it was a very good suggestion to improve the paint coating, well
worth ten minutes of prevention.
