A buddy I worked with used it on his Sig 226 and when we went shooting in Nov it was 32 out. His Sig kept jamming while my 4506 with surplus CLP kept chugging. Told him to ditch it and use something else.I remember when Frog Lube was all the rage. It was crap IMHO. My guns were stored out in our family room which gets down into the low 60's during winter and they just flat out wouldn't run. Thankfully I only tried it on a couple of guns and cleaned it off and started using "real" gun lubes again. But Frog Lube is non-toxic and mint flavored, so I guess if you were one of the kids that liked eating paste in grade school, it would be perfect.
