I'm very frustrated.
The only silicon based lubricant I've been able to find locally at hardware stores is "DuPont Teflon Silicon Lubricant" in a spray can. I've used it on my flashlight O-Rings for a long time, but I want to find something better... the spray is hard to work with, too thin to last very long, and I don't like the smell very much. I'd like to find a thick silicon based grease to use instead.
I've looked around in local hardware stores for silicon grease... but with no success so far. All the idiot salespeople look at me like I'm from another planet or something... I keep asking for "Silicon grease to use on rubber O-Rings" and they ask me why the O-Ring is leaking, or direct me to the silicon glue and/or calking in a tube adhesives. It's like talking to a brick wall - I tell them that I do NOT want an adhesive, I do NOT want WD-40, and that I do NOT want Lithium grease or petroleum jelly... I patiently explain that petroleum based compounds dissolve O-Rings and I get a blank stare in reply.
What is the most commonly available Silicon grease? What is it used for? Should I be looking in different places than hardware stores, like maybe plumbing, electrical, or hobby specialist shops?
Best wishes, and thanks in advance!
