restoring pot metal

I have used Alsa Killer chrome. After I got the hang of proper application it turns out a nice shiny reflective surface, but not even close to real chrome. Not a substitute in my view.

Silver solder melts at over 450 degrees where the specialty pot metal rods are under 400. I have used Muggy Weld and, so far, found it to be the most satisfactory pot metal rod.
