almost free rust removal using battery charger and washing soda?

Funny that this topic should come up again. My buddy and I were working on his car and we had a brainwave...

A few years ago I talked with a guy that wanted to derust the shell of his Barracuda with this method. He was going to dunk it into an above ground pool. Not a bad idea eh? But what do you do with all the crud and sludge?

Well we were talking about this and figured out you could rent a big metal dumpster, drive your car right into it, fill it with water and soda, connect your electrodes (you need a welder or something at this point) and the whole dumpster would be your anode or whatever you call it! I think it's brilliant! The rubber tires will keep the car isolated from the metal anode, it's all perfect!

When you're done just drain the water (it's harmless dirty water, remember) and call the dumpster company to come and pick up their dumpster! All the crud and rusty sludge will be their problem! hahaha..
