Yeah I've done one bit of pot metal on an autoreelite. My kit is a triple chrome kit so has a flash copper and a copper plating tank, so I do both of them before the nickel. The pot metal came up well, but you've gotta be real careful when you dip it in the caustic cleaning bath, as it just chews it up in no time! I actually wrecked one as I chucked it in and walked away and left it, came back and it was shagged! Luckily I had a spare. The copper coating allows you to fill some of the pitting that old pot metal generally has.
