Three-Way Gun-Protectant Test
Although our test is not definitive, we concluded that while Fluid Film offered excellent protection for a while, we’d prefer to use S&W’s Premium Lubricant & Protectant on our guns.
We have several times tested oils in a simple comparison to see which offers better protection against rust than the others. We’ve run this test with several ancient and modern fluids by the simple expedient of grinding off a piece of steel, marking off areas on it, anointing each area with different oils or greases, and letting the steel bar sit outdoors for days or weeks to rust. After a week or two we generally apply some salt to make the test somewhat tougher.
A manufacturer’s representative read our most recent report (July 2010) and offered to put his product, “Fluid Film,” to our test. The product is made by Eureka Chemical Co. We received a sample in an aerosol spray can holding 11.75 oz. The product is labeled as a penetrant and lubricant, and is supposed to give long-lasting rust and corrosion protection. The product is wool-wax based, which is lanolin. In addition to its penetrating and lubricating qualities, it is claimed to not harm paints, plastic, or synthetic rubbers.
