I am a dyed in the wool Froglube convert. Just make sure to follow the directions. I say that because most people who seem to have a problem with it don't.
The only thing is it is kind of a one-way street. They recommend using the solvent to get rid of what petroleum products are already there. Then just the FL CLP from then on. One issue is the people who get everything off, use the FL CLP, and then "just put a thin film of gun oil on it". Yes, there will then be problems.
After about the 2nd or 3rd application (easier than the 1st) you'll be surprised how easy your gun is to just wipe off.
