Cast Iron Rust Prevention?

My wife bought this bird bath that is made out of cast iron. Not really
sure if it is meant to be a "practical" bird bath or not....it rusts almost
instantaneously when it gets wet (of course...especially the bowl where the
water collects...)
I tried putting like 3 coats of clear laquer on it...and that seemed to have
absolutely no affect whatsoever. Is there a rust prevention product I could
use in this case...one that is clear so as not to change to appearance of
the bird bath?

Fill the bath with phosphoric acid?

(clip) ^^^^^^^^^^^^ I don't know about clear, but this is what I suggest. Line the bowl with fibreglass/resin, like you would use on a boat. You might add some lampblack to the resin so it does not look like a fibreglass lining. I would prime the rest with a good rust resistant primer, and paint it black. A flat or satin finish would probably look more natural on cast iron than gloss.
