Was that an electrolysis bath with the body?
Yeah that was a bit of a science experiment we decided to try. Didn't have a big enough tub and had to put together a rigged up contraption to get it to work. It was pretty amazing how well it removed the rust though. It was down to bare metal after a couple hours in the baking powder bath. Probably not the safest configuration, but it was effective. We will do the same thing on the Pepsi cooler but will plan a bit more in advance on how to rig it up.
