I was searching for a silver solder for tungsten when I found this.

Looks like they have some new stuff that does vertical better. I also noticed they sell a galvanize touch up. Anyone try that? I am wondering if it could be used on the pinch area of a door skin/frame?
And, I am still looking for a low temp way to solder tungsten, like to a circuit board.
