I believe you got caught up in some marketing mis-ques! I know, because I also scrutinize (OCD) purchases and thought there were different Silglydes.
Furthermore, if you look at their MSDS you will discover that SilGlyde is not a true silicone grease like the Motorcraft or Dow products. SilGlyde contains less than 13% silicone.

Amber vs. white/clear? An older tube will turn amber. .

I'm aware Sil-Glyde is not a high silicone product. I purchased because of the many favorable recommendations, the price was right and I was very disappointed with the Permatex green. I just threw their specs out there for discussion.

As for coloring, I don't think it was aging, I looked at many tubes at a few locations, all had the same appearance..

I'm glad you knew about the silicone content, because I didn't!

Ya, I need to get off my high horse about Silglyde. On different forums I get the perception people think it is a silicone lube and I have a compulsion to want to educate them about it.

I, too, had bad luck with the Permatex green (and others) and as noted above, I went back to Silglyde based on my experience and the excellent recommendations of others. It's hard to use old school products when there is some much high tech., new "super stuff" out there.

My older tubes do turn darker after several years. Maybe some batches come from the factory different colors? Who knows, who cares. But, I don't think they make different formulations based on my phone call.

It's been fun. Take care.

Heres another Brake Caliper grease from Napa #97008..more expensive then Sli-glyde ..closely resembles the 3M and Ford product when looking at the MSDS @ http://www.super-lube.com/silicone-brake-grease-ezp-54.htm... ..a pic of the tube @ http://www.super-lube.com/silicone-brake-grease-ezp-54.html.. also comes in a 100% version of "polydimethylsiloxane without the PTFE additive @ http://www.super-lube.com/files/pdfs/PTFE%20-%20how%20it%20works.pdf... and I am guessing the same or similar as the AC branded product...It doesn't seem the "links" want to connect...

Check your urls above and replace "html.." with"html".

Superlube has a.pretty good reputation, I would try this. How is the consistancy? It is my opinion that the trick is to balance water washability with easy flow.

Motorcraft XG-3-A is all I use caliper slide pins, it works great and lasts.
 
I started using the 3m silicone paste and after a year of off roading in my jeep it was still wet. I was a little hesitant to spend 18 bucks on it (from eBay) but I think the one tub will probably last me a lifetime! I believe from my little bit of research the acdelco is very similar (don't know if its made by 3m or not..can looks the same)by though they did update the packaging on the 3m

I have primarily used the XG-3A Motorcraft Brake caliper grease/dielectric compound for years. Never any issues with it. Seems to be good stuff. I have used nickel anti-seize in a pinch. No issues with it personally but I have heard of enough problems that I prefer the dielectric. I even used the XG-3A to coat the stopper in my bathtub after it seized up. Removed cleaned and gave it a good coating. That was about 4 years ago so I guess it works on brass tub stoppers as well lol

Be careful not to get the "regular" Superlube with Teflon, which is usually what is most available on the store shelves. A study of their web site shows that it is not compatible with EPDM rubber, which is common on vehicles (not sure about brakes).

I was shocked when I learned this. http://www.super-lube.com/files/pdfs/Super_Lube_Compatibility_Chart.pdf
 
Yeah you want the Superlube that is labeled "silicone" and not the less expensive synthetic grease. Same goes for Permatex, silicone instead of synthetic in the interest of rubber (elastomer) and pre-existing grease compatibility.
 
I used to work for a company that manufactured kiln grease (high temp grease w/ moly & graphite). Got a tube free from the R&D lab and I've been using that on brake parts for years.

Hmm, Polypropylene, that is what some plastics are made from, no?

In that case perhaps Sil-Glyde may not be compatible with certain plastics?
 
Hi, I need to use something to lubricate my caliper pins.

It seems that some of you had problems with the Permatex Green brake stuff

is there anyone that has used Permatex 24115 Hi temp silicone (the red label)

http://www.amazon.com/Permatex-24115-Cal...;keywords=24115

and care to comment?

In the MSDS the Permatex red seems to be very similar in ingredients to 3M #8946, apart from the moly added.
Can it be a good substitute to 3M or Motorcraft XG product?

Also, can anyone reccommend a place to buy any of the above in Europe? They only seem to be available in the US and the shipping rates are outrageous.

Thanks for your time

I use this, got it on Amazon. Seems to go fast there and isn't always available. One bottle should last me the rest of my life.

It gets good reviews. I've used it on my Subaru caliper pins and inside the caliper boots, no swelling and seems to be doing a good job. I also used it on the side of the brake pad shim that contacts the brake piston.

No idea how to get it to Europe, shipping is a b*itch.
