Hi, Jeff, I use a "Nimrod Solderpro butane torch" and "Fryolux paint"
You "Paint" the liquid (Which is a combination of solder and flux) on the area needing soldering then using the Butane torch apply heat and you get a permanent good looking join,
It is the easiest way to solder I have come upon.
WARNING the solder/flux mixture is very toxic, don't let the kids or the pets get to it!!!
