Straightening up the shop today, ran across some of this (http://www.amazon.com/Radiator-Specialty-Plumbers-Silicone-Grease/dp/B0009PY4OE) wondering if it can be used to lube the piston seal for replacement in the tube...

i would try it, especially if it says it has no petroleum in it.

I've seen that stuff in the home stores and was wondering if it was the same as dielectric grease. I imagine it's probably the same stuff. I use dielectric grease to help with assembly and the usual lubes throughout.

Some rubber type grases are ment for assmebly only
and have no long term lubing ability.

The conventional "wisdom" says to use dielectric silicone grease for the seal and compression area. When I posted a question about it in the forum I'm banned from, I got few responses and even those from the "honchos" never really answered my question. I did receive a lot of pm's and emails from people afraid to post openly.

Several knowledgeable home tuners recommended SuperLube instead and to not even bother with silicone (I have several tubes of the dielectric stuff for automotive apps). So, I've been using SuperLube since and it works fine. Beside being synthetic, it also contains Teflon. I have no dieseling or detonation problems but I go lightly with lubes in general. Silicone may be more appropriate for guns with leather seals, but that's just a guess.

I've been looking for Super-Lube locally, haven't stumbled upon it yet, although there is a hardware store across town that has a little of everything. I don't like ordering small things off the internet, shipping costs more than the product...

Thanks again everyone for sharing your expertise. I think I'll keep the Silicon Grease handy, might get me out of a pinch sometime...

i orderd super lube for 9.95 shipped for a 3oz tube.

I found Super Lube at the local Harbor Freight, for $4-$5.

Just got back from Harbor Freight... they must have been out last time, $4.29.

Thanks guys!

that's funny harbor freight didn't have it the last time i was there either.

Harbor Freight is bad about moving stuff, you gotta ask where it is, or at least it's that way here.

The hook was full and then some, might have just got in stock.

Pure silicon is a great carrier for powdered moly.

I also use a 50/50 mix of SuperLube and moly instead of the 50/50 mix of moly and 30wt non-detergent oil recommended by some. Works well and stays put. I don't use it in the powerplant but in trigger assemblies, pivot points, etc.
