Got it friday, tried it out. Strong spearmint smell and it feels more like chapstick on your fingers than a solvent. Smeared the paste all over my p99, hit it with a hair dryer, and wiped it off. Rag was quite dirty. Afterwards the gun kept a certain slickness to it for several hours until I'm guessing it impregnated the metal. I did another coat with the same effect. Gun looks like new and functions great.
Its lubricant properties are fairly good, but its cleaning properties I was VERY impressed by. Having the ability to just put some of it on your fingers and rub it over the gun without ruining your skin is a huge advantage.
Worthy purchase just for its green factor. If you clean a lot of guns or clean often, it's clearly a healthier choice.
