Never used it, and the product seems to me to be more of a cleaner than an oil, and the gunsmith uses it as such. After liberal spraying he blows the mechanism with compressed air and wipes up what becomes visible on the exterior of the gun.

I would think that forced air would drive some of that dirty slurry further into the gun.

Although he rejects the practice of applying grease where moving parts bear on metal at one point, saying that the substance will hold particles and can become a deleterious grinding paste, later he doesn't let a "foolish consistency" keep him from applying grease to an ejector spring.

He's a professional, but some would question his saying that engine oil is as good as a gun oil, as do not engine oils have some corrosive agents to simultaneously clean and lubricate? (The interviewer does sound taken aback with what he says about the suitability of engine oil.)

Thanks for the link, and I enjoyed watching and am always interested in the subject of cleaning technique and what adherents say about their preferred products.
