I have used FrogLube for years. I bought a small container of both the liquid and paste to try. I liked it so much that I bought a gallon of the paste and put it in a large crock pot. Even though you do not need to keep applying it, it makes cleaning so easy and the crock pot eliminates the need to heat the metal. Just place the disassembled parts in a strainer, leave submerged for about 15 - 20 minutes, remove and wipe clean. It works great in the dry, dusty desert here in southern Arizona. The main thing I use it for on my airguns is the barrel. I put the liquid on a patch and run it through the barrel. I then run dry patches through until they come out clean. I do this 2 or 3 times. It leaves the barrel nice and clean, provides protection against corrosion, and has not affected the accuracy of anything I have used it on to date. I even disassemble my knives and treat them. I recommend that if anyone is unsure about the product, do what I did and buy the 4 oz. containers and try it out.
