I see a lot of guns that have been frog-lubed. A few pros and cons:
* Pro- it makes the gun a lot easier to clean once it has been treated and heated.
* Pro- lubricates well, makes things really slick, like a lot of the "thin film" lubes.
* Pro- treated guns seem very rust-resistant, but no more than Weapon Shield or Eezox.
* Con- it smells like wintergreen oil, so it will make you stand out in the woods. I remember a lube back in the '70s that was made of banana oil, it worked well but you smelled like bananas.
* Con- when carbon from firing the gun mixes with the frog lube, it gels up and forms hard little goo balls that will eventually stop your gun.
* Con- treated guns sweat the frog lube out of the metal as they warm up.
* Con- really cold weather makes frog lube gel up.
All in all, frog lube isn't bad, but it isn't all it's cracked up to be. Proponents say it's non-toxic and you can eat it if you want to (I wouldn't). I am still undecided as to whether I like it or not. I prefer Militec-1, personally.
