I finally gave in and decided to try this stuff, now I'm tempted just to buy the 5 gallon bucket of it!

Here is a coin door that was in miserable shape:

Put it in for about 15 hours (forgot about it!) and its not new, but it looks great!
First pull out of the pan, no scrubbing:

After two minutes of foil scrubbing and a wipe down:

Next I plan on buffing then I suppose I'll need to hit it with a little spray can clear coat to keep it from rusting pretty soon after?

I had meant to remove the lock but forgot... Didn't think about the hinge, but good idea.

I was thinking about clearing just to seal the air and moisture out assuming that a good portion of the pitted metal would be susceptible to more rust.

Ok, here are the other results. The coin entrance plate was so pitted that it doesn't look very good - but still loads better than the rust bucket version.
