Never tried Frog Lube........hell, I never heard of it either!
I have been using a lube for 30 + years now. It is called RIG #2 Oil, NOT to be confused with RIG Universal grease. They only thing they have in common is that they are both made by the same Company (Birchwood-Casey).
Rig #2 oil cleans, lubricates and prevents rust. The really nice part of this product is that it evaporates and leaves a dry lubricant behind. I like that because the lube will NOT attract dust, grit or dirt. It will also not get all over your clothing because by the following day the carrier has evaporated leaving behind the protective coating. I have NEVER had any rust appear on any of my firearms, even when caught out in a down pour during a Pheasant Hunt. I use this product on tools, the cars, the motorcycle, and all around the house. IT IS GREAT!! It's also nice because you do not need a separate solvent. This ONE product will do it all. AND......it even smells good.
