I was inspired by PredictaNoob to try electrolysis rust removal (http://www.videokarma.org/showthread.php?t=247755) on an Admiral HV cover.
Here's the rusty, painted cover.

First, I removed the paint using Citri-Strip. Then, mixed up a bucket of electrolyte. I'm using Arm & Hammer washing powder (Sodium Carbonate) and about an amp of current. The positive lead is connected to a sacrificial cold chisel. The negative lead is clipped to the cover.

I let it run overnight and it worked out very well :)

Finally, a little black satin enamel paint.

It's a messy slow process, but it does work well. I think I'll stick with Naval Jelly for small parts and smaller patches of rust and use this technique for really rusty parts that are easily submersible.
