The trailer was commercially made and at one time pin striped and
probably painted red..but now is pretty much a solid sheet of very
thin rust.

Probably the best thing to do is find a tank blaster and have it sand
blasted, but other than a cup brush and a day grinding the rust off,
are there any other options? Some chemical or paint that will stop
the rust and coat existing rust? Its very well made with lots of
angle iron and channel and its gonna be a real PITA to wire wheel it
clean.

Just pondering. Pretty is not important. Utility and cheap is. G

Following those links on electrolysis someone posted yesterday, I came
across your exact problem and the solution:
