Freek'n love it! I live for this crap. I've done rust removal with that method using baking soda as the electrolyte, worked like gangbusters. And just finished my second brass head badge using acid but no current.
Had about half the tutorial wrote be for it was deleted by accident(wife).
but I like your method as well.
Sooooo what if I used current and acid kinda like nickel-plating backwards.
And how would running the current through a transformer affect it?( i.e. high volts-low amps)
I'll work on it next weekend.
