This is probably not what your looking for, but I think that real chrome in a can looks pretty good. One of my customers wants me to try it on some of his pot metal. The kit is around $120.00, and you'd prep the piece like any that would be based and cleared. As you know, pot metal sucks. This seems to be a cheap and easy way of restoring it(to a chrome finish).

Good Luck!
