Review on Forney 48571 Super Sil-Flo 1/8-Inch Brazing Rod, 1/2-Pound by Jason Cho

I have brazed refrigerant lines for the last 28 years and have always used 15% Sil-Foss with no flow problems. or heat. This type works fine, but it seems to need a bit more heat at the solder joint to make it flow, and as for the back and reverse solder joint, the solder runs off the solder joint. It may take longer to get used to and I'm not very good at it and I'll get the hang of this type of solder. I will probably buy this product again as silver prices are so volatile and so far it has worked very well.
