Ah Shortleg,, do you have any more info?? I've always wondered if that was possible. The idea of electrolytic rust removal always comes to mind.
I live where they spray that damn liquid rust on the road and I lost one real nice truck to it. The truck came from Georgia with no rust and 5 years later the frame was almost gone.
The problem is that my driveway is shaded and it isn't paved, if the vehicle doesn't get driven every day it quickly goes to hell.
