Several years ago, my neighbor's son did a science project in high school. He did a study on corrosion preventatives. He used baby food jars filled with distilled water to minimize effects of additives. He also used 2 different kinds of nails, made of different alloys . Both nails, one each, were coated in a uniform method with a single wipe of the all of the preservatives using a fresh portion of the application cloth, and placed in the jars separated. All jars were labeled with the preservative and the date. The jars were all set in specially made racks with the labels visible. They were checked periodically analyzed, and a log kept. The project lasted a full school year, 2 semesters. Every kind of oil, grease, lubricant, preservative, assembly lube and synthetic and petroleum based product imaginable was used. Yes there were hundreds of jars, which is why he chose baby food jars.
The end result was that when the test was over, only ONE product left the nails absolutely rust/corrosion free. That product was RIG (Rust Inhibiting Greas), a gun preservative. Second place, with only a touch of rust on the point of one nail, the untreated one, had a little rust, The rest of those two nails were literally unscathed. That product was CLP Break-Free.
I wasn't surprised at the performance of the RIG, but was astounded at the CLP. I personally provided every lubricant and gun preservative I had, which was many, and I trusted my fine guns to them. I was very dismayed when I saw that many of the nails treated with what I thought were first class preservatives were nothing but piles of rust powder in the bottom of the jar, completely gone. The boy's father provided the CLP, I provided the RIG and Anderol, along with other high zoot chemicals.
The conclusion was that for long term storage, RIG can't be beat. For regular use,
CLP beat everything else hands down.
Naturally, for long term storage, I coat things with rig. For routine maintenance and cleaning, I use CLP. Now, Microtech and conventional wisdom say to NOT use products that have teflon in them for automatic knives, but my own experience shows that very careful sparse application of CLP, allowed to drain overnight, and wiped dry the next day prevents a build-up of teflon that could clog up the works, yet still leaves a protective film. Microtech themselves now recommend RemOil, which also has Teflon in it. I haven't subjected RemOil to the torture test that CLP passed with flying colors, so cannot comment on it for dependable rust/corrosion protection.
After seeing with my own eyes the utter failures of vaunted and highly advertised rust preventatives, and the singular superb performance of the two winners, I'm converted.
I'm convinced that CLP offers unmatched corrosion protection along with excellent lubricating qualities, so I use it on ALL of my guns and knives. I've yet to have a failure of either lubrication or corrosion protection.
BTW, the WD40 treated nails were the first to begin rusting.
