I just put a set of rusty PW staple end trucks in Metal Rescue. I'll check in a few hours to see if it really works.

I would be interested in how it goes, thanks. I've heard of it but not used it recently.
I soaked the trucks for 4-5 hours. The came out very clean all the rust is gone. However the paint on the couplers and the any diecast surface came off. What I like is that I just set the trucks in all assembled and the solution did not hurt the wires, shoes. These had a good coat of rust over most the surfaces, I didn't have to brush, scrape of use toxic stuff the solve the problem. The tray for the Log car went in too and most of th paint came off. I dont think is it paint seems more like bluing. It will take bluing off.

Blueing is rust
Using electrolysis to remove rust is very effective, does not harm paint or non-rusted metal, and is widely used in the restoration field of almost everything made of metal. Very simple and cheap, the process can be used on any size part with a little imagination. I have used it effectively to remove rust from tools, track, and pieces of scrap metal used in projects. After removing the rust, wipe on a very light coat of oil to protect the metal from rusting again, and it will.
The process will not attack the base, unrusted metal. Rust is initially formed through electrolysis action, and we are using the same method to remove it. If the rust has pitted the metal already, the metal will remain that way, but the rust will be gone. Once the rust is gone, no further action will take place on the remaining metal.
Note that the closer the electrodes are to the rusty metal, the faster the reaction will take place, and the more current will be used from the power supply. Depending on the amount of water, the current being drawn, and the time the process is running, the water solution will get warm to hot and start evaporating. This is normal. If necessary, just add more water.

I am glad to see Metal Rescue worked for you, if you have any other question about our products please don't hesitate to ask.
The die cast parts are chemically blackened zinc. The process you used has removed the blackening from the zinc. You could check the Birchwood Casey web site to see what is available to reblacken it.
