Kester sold a formulation of their solder that was supposed to be very close to Deans solder. I tried emailing them about it, KE1119 - 18ga solder and KE1120 which is 23ga. Both are 2% silver. They never replied and I haven't had time to pursue. I have been warned if we find it, its expensive, but I don't know exactly what that means.

Guess I need to try calling a real live person this time.
