WPT- Preventing rust is accomplished by putting a barrier between the gun metal and other molecules that will accept electrons. Do you really have any data that compares the electron flow from the gun metal to an electron acceptor under various condition. This would be necessary to conclude that Clenzoil is the most superior product for rust inhibition.
I can go one better than that, I have proof sitting in my safes ... When only the best will do "Clenzoil" and the Clenzoil people have any and all the data you would want ... I do not keep that data on file and go by what it does, not what people say it can do ... WPT ... (YAC) ...
My Dad came upon an ol gun buried in the mud many years ago and he brought it home I got the priveledge of cleaning off the mud and dirt off and out of it. A single barrel 12 gage. The wood was not salvageable. But anyway I cleaned this guy to where you could eat off it. Opened 4 cans of Valvoline and dumped it in a tub just big enough to hold the oil and the gun parts. let it soak in there for about 4 days and started with one piece at a time. I cleaned up the gun metal parts and Dad he made the stock and forearm. The barrel was pitted but not to where it needed bored or anything like that. Dumped the oil and refiled it with 4 more new cans. My uncle owned a Gas station then. Got the oil cheep. Would have used resicled oil from the dump tank for the first go round but he, my uncle had just had it empted. The gun turned out to be a pretty good shooter. I wanted it but many years later Dad sold it. I was scremin mad. (Rich.inAz.orinnameonly)
WPT- In exposure tests, Brownell probably did the best one, RIG came out superior to the others test for rust prevention. The tests involved coating, one time, sheets of metal with different rust prevention lubricants and placing them out side for one year.
Rust prevention is only one factor in evaluating a gun lubricant. RIG does not have great lubricating characteristics (poor lubricity) but is great for rust prevention. Clenzoil is a good thin lubricant and also works as a cleaning compound. This is accomplished by adding solvents to the oil base. It does lack adequate adhesion to be a superior rust prevention treatment.
I have used Breakfree CLP on my guns for many years. I discovered it while hunting in the San Francisco/San Pablo Bays for Canvasbacks, Bluebills, Spoonies, Mallards, Teal, etc. I will guarantee you, there is nothing that will rust a gun faster than shooting over salt water marshes and bays. I shot a BPS pump for years just for this type hunting. I was a fireman at the time (which is how I discovered it since that's about all we used at the fire hall) and shot approximately 60 days of every 93 day season for many years. There were many times I would just come home from hunting, leave the gun in the boat with just a quick wipe down, inside and out, with a cloth dampened with Breakfree, and head for work, only to go back out and hunt the next day. I would totally tear the gun down ONCE at the end of each season, unless I shot in a really bad downpour, and put the gun away for the year. It never showed any signs of serious rusting, even after about 10 years of doing this. Sure made me a believer in the product. I suppose there are others that are just as good, but, with no rust after 10 years of Bay shooting, how could another product be any better?.... Dan Thome (Trap2)
