Brian,
I have used MuggyWeld a fair amount while working on parts for old tablesaws that are no longer made. I also used it as a quick-and-dirty way to fill the pinholes in my brass radiator tank and it hasn't leaked since.
I don't know whether the strength is the same, but I have been unable to break the parts apart that I "welded" with this stuff. In my humble opinion, it's a GREAT low-heat brazing product that works especially well for pot metal. It's just as easy to use as plumbing solder. I plan on using it to repair my own hood ornament when I get around to that.
You have to use their flux solution, but it makes it easy for a novice like me to tell if you're getting the right amount of heat going.
I have been very happy with it.
Best,
Jim
