While there is good information contained in that article, I have always disagreed with his assessment of WD-40's resistance to corrosion. And Brownell's conducted a rather extensive test which helped me reach that conclusion. It a test it conducted WD-40 scored at or near the top in regards to corrosion protection. (It appears as last product tested at the bottom of the page). "WD-40: WD-40 was never meant to be a lubricant – it was designed as a moisture displacer. It’s far too light for any load protection, has incredibly poor corrosion resistance, contains zero boundary lubricants, and rapidly oxidizes to form a sickly yellow varnish (hint: this is not good for delicate internal lockwork.) There are those who will defend this stuff vehemently, but then again you can still find people who think smokeless powder is a passing fad. Just. Don’t." Gun Cleaning Clinic: Knowing the Limits of Rust Preventatives | World's Largest Supplier of Firearm Accessories, Gun Parts and Gunsmithing Tools - BROWNELLS "WD-40 has been around a long time and earned the reputation as an excellent rust preventive for exterior surfaces of firearms. Test plates show excellent moisture displacement. Minimal rust formation is present; almost no pitting is visible after degreasing."
