Yep, It takes oxygen to make rust. Good dry water doesn't rust anything.

Like the old Coke with anail init. The nail always rusted off above the
liquid and was siney clean below the Coke.

Bottom's up!

Yeah, a great idea. I long ago put a copper extension on the drain,
with a petcock that is used so infrequently I need pliers to get it to
turn. Worse, I have to move a ton of junk piled in front of it to even
see it.

I'm still wondering if a damp tank rusts faster than one submerged in water.
