I saw this quote on a thread at PF.Com this morning:
I keep hearing and reading various lubricants and finishes “penetrate into the pores of the metal.”
How the heck did this get started? Does anyone actually think their gun has pores at its surface? Just for the sake of argument, lets say it does have microscopic pores (it doesn’t). And lets say the lube/finish (usually an epoxy based finish that continues to offer “corrosion protection” after it has worn off) does penetrate said pores….that mean the lubricant needs to have nearly no surface tension and no viscosity, both of which are necessary to act as a film layer lubricant. And if said oil has such a low viscosity, it will need to have a low molecular weight, meaning it will evaporate quickly. And this argument ignores the fact that the lubricant will need to overcome the bubble pressure of those microscopic pores before penetrating them (not gonna happen).
The author of said quote is a Certified Pocket Protector Science Bro; and an expert in the whole “metal stuff” field. I on the other hand am the gun industry Jeremy Clarkson, prattling about power while sliding around corners like a yobbo. “I don’t care why it does that James, only that it goes fast.”
Back to the point of lubrication and the sudden and massive increase in miracle gun lubes on the market. If someone is telling you that their new miracle lube “penetrates the metal’s pores” then they’re either 1) ignorant or 2) lying. Being ignorant isn’t so bad, because they’re probably just repeating the company line which is more marketing than science. Lying is pretty bad, and I generally don’t believe in attributing behaviors to bad intentions when incompetence is a better answer.
You miracle lube won’t penetrate the pores of your guns. In fact, your miracle lube probably isn’t better than engine oil at keeping your guns running, but don’t tell anyone that, because then they couldn’t sell you little bottles of ToadGoo for $20 for four ounces. Meanwhile, a quart of 5W-30 will do just as good a job at lubricating your gun and will last you nearly forever.
