I have been using Froglube for well over 4 years. I love the products smell, it doesn't burn my hand if I have a cut, and it really does break down carbon. However, whenever I shoot a gun I have not used in a a while it's gummy and sluggish. I have a 1911 that I have not shot in two years. I went to go lube it up before the range use and the entire gun is locked up. It's so gummy I can't work the slide. I have to use a heat gun just to partially rack the slide. So I am done at this point with Froglube. Anyone have an any experience with fire clean (aka Crisco), slip 2000? Or do I go back to mpro 7, with hopes and breqck clean( these worked butbI could not stand the smell). I don't want to grab a gun again in a year or two and have the same gummed up gun.
