I have read all the propaganda for it plus was given a gallon of the stuff. I am inclined to think it has a tendency to evaporate over time, so leaves something to be desired as a lubricant. I am less than impressed with it as a cleaner. I use it for things that aren't critical.
What I use most is surplus 'oil, light, lubricating' that I got for 50 cents a gallon. GI bore cleaner used to be dirt cheap, too, and I still have a supply of that. I also made up some of Ed's Red as a bore cleaner and it seems as good as anything else.
Always wondered who had time to evaluate all these wonder products.
