Grease

Got to thinking just recently about lubricants--namely, GREASE. Has anyone on here had any experience or occasion to look into the use of "Plumber's Silicone Grease" on firearms--specifically, slides? It sure does stand up well to water and seems to do admirably at its job--to lubricate sliding parts. Would appreciate hearing any pros and/or cons from the membership. Although I'm a fluid power engineer by trade, I've never used silicone grease on anything other than faucets and in water-proof wire nuts for splicing electrical wiring. Stuff is expensive enough, though. H-

New2, the plumber's grease I use is pretty viscous stuff as you might expect, being it's job is to resist H2O. If you want to check it out, I buy mine at Lowe's Home Improvement. You'll find it in the plumbing department with the tools, torches, solder, etc. The trade name is "Gunk" and it's marketed by Radiator Specialty Co. out of Charlotte, NC. Comes packaged in a fifty-cent piece diameter sized, white plastic cup. (about 3/8 inch thick) Pretty expensive for the amount you get. I expect that I could find it at a better price if I just took the time to shop it. It is a "white" (clear) grease and I find all sorts of uses for it--especially where you don't want the risk of staining.     What white silicone grease do you use and where do you buy it? I see all sorts of it on line. Like I said previously, there are wire nuts (again, available at Lowe's) that are filled with white silicone grease. I use them to waterproof splices in the wire of my buried "dog fence". H-

I've been using TW25B, an extreme performance synthetic grease made by Mil-Comm Products Co. After reading a review, I bought some for my AR, but now use it on all my guns. Not cheap, but one tube will probably last a lifetime.

When I use grease on firearms, which is not very often, it is shooters choice all weather high-tech grease. This grease was recommended to me by a retired Ord. Maint. Officer turned gunsmith, who worked in the infantry weapons shop aboard Camp Lejeune. He built me a couple of awesome 1911's and this is the grease he swore by for the slides.
