Here is a pot metal rear window frame from a 1948 Buick convertible in need of a lot of work.
With the corroded portion of the pot metal cleaned up its easy to see the extensive damage in need of repair.
Almost any heat source will allow you to solder with Super Alloy 1.
Maybe you would like to use a soldering iron to smooth out the finish before sanding. Go ahead, it works!
After sanding and plating, the pot metal window frame looks like it came from the factory.
