Silicone Paste question

[jacked_72]

I've seen references to the stuff, but the only product that I've seen that is actually called "Silicone Paste" is the stuff made by 3M.

Is regular old silicone grease in the plumbing isle at Home Depot (like for o-rings) the same stuff?

How about Super Lube?

I generally see the reference to silicone paste in connection with brake jobs.

Are you thinking of this:

It is basically the same stuff, but is actually made for use on brakes.

 

[jacked_72]

No, the stuff I've seen is the 3M stuff in the first link. It is clear and not specifically for calipers. I'm not sure of the advantage, but I think its not supposed to dry out with the heat the way conventional grease does. The Permatex stuff may do the same job, and its probably a lot cheaper. I just that thought that upwards of $25 for the 3M container was a bit stiff.

If 3M is calling it a "Silicone Paste," that would make me think it's probably very viscous - thick. Dow Corning #111 is like that; it's a very thick silicone grease that sticks to O-rings very well.

That SuperLube #21030 is a thin silicone grease that flows more easily; less viscous.

I've got both the Dow Corning #111 and SuperLube #21030. I use the thick Dow Corning on O-rings that are going to be exposed to water and the thinner SuperLube for lubing my Snap-on ratchet internals.

I depends on what you're using it for. When I lube up my MAGLITE flashlights, I prefer to use the thinner SuperLube for the O-rings because I don't want a thick grease on the aluminum threads that are right next to the O-rings.

Dow Corning 111.

I've been using Permatex dielectric grease for caliper pins, but I do believe I'll be ordering a can of that stuff to use from now on.

I have a can of the 3M paste and it is thick, and stays in place very well. There is a brush built into the lid like the old pipe dope cans, very handy. This stuff seems to go a long way, been using this one can a long time. And on a lot of things. Seems to work on most rubber things around an auto, works very well on weather strip around the sunroof on the SWMBOs MINI.

I just used 3M silicone paste today on the inside of a rear main seal before installing and and shift shaft seal. I typically put it on caliper pins and o-rings. It's good stuff. The Dow Corning 111 is also good. I believe it's what is recommended on Honda caliper pins from the S/M.

I use the 3m silicon paste. That can will probably last you the rest of your life unless you start eating it, in which case it will probably still last the rest of your life (however short that may be).

I would say that a can lasts me several months in a professional shop and I use it on just about everything rubber

I wouldnt use the stuff from the plumbing aisle for the same reason I wouldnt use the thread sealant from the plumbing aisle on a car instead of this.It may be the same it may not be, either way its not worth the few bucks I might save doing the job over because it causes problems. Its probably a very close cousin though.

There are good thread dopes in the plumbing aisle, and crappy ones.
Rectorseal 5 is way better than that Permatex BTW, and I have spotted that in box stores.

I wouldn't use the o-ring grease from a box store though. You don't know if it is actually silicone or not. If it has ANY smell, don't use it. It is **** (and a lot of the o-ring greases I've see in the hardware stores are stinky).
Real silicone grease should be putting off no odors or volatile chemicals.
