Springer Lubes: Something New to US

[Sky]

I'm tuning a few springers now, for myself. I have been using a moly paste from Air Venturi, and its pretty good. But it ia wet and hard to apply perfectly, and after doing and redoing afew guns i dont know how little or much really helps.

I started looking at the krytox and ultimox stuff, but i like the idea of moly because it will bond to the metals.

So doing a search here nobody has ever mentioned rocol's dry moly spray. It is an aerosol that deposits 70% moly and dries for handling. A solvent and resin, with a ton of moly in essence.

If i can get some it will be cheaper than the space age plastic lube, and should coat the things evenly, especially insides of springs.

Anone used it, heard of it, used something similar? I sent some emails to the US distributors and am trying to get a can.

I used sprays like that in the distant past. They provide a quite durable, but thin, dry layer. This is good for high temp, metal to metal contacts, where you don't want to have any greases. It would be good for coating metal spring guides, top hats, thrust washers and similar stuff. I probably wouldn't use it on a springer mainspring, or around the piston seal.

Why?

Why?

Unless you have exceptionally well fitting guides, dry springers are very likely to twang and buzz. A very thin layer of something like velocity tar (JM) will tame that. On the piston seal, the spray moly would form a layer, that would likely change the fit of the seal in the tube. Also moly is more a metal to metal lube. Krytox, or moly grease would be better.

Perhaps this will help...........

Years ago DriSlide was touted as a good springer lube since "supposedly" the carrier would evaporate leaving behind a film of dry molly...........

I didn't like it when I tried the stuff because the stuff inside a springer would "diesel greatly" if there wasn't sufficient time for the carrier to evaporate. LOL, the carrier didn't always evaporate completely inside the confines of a sealed springer receiver even after sitting for a day.

"i like the idea of moly because it will bond to the metals."
Well....most piston seals and spring guides are "plastic", not metal. There is some benefit of a molly film between the piston and receiver as well as other sliding metal parts, however I've found that "plastic in the Krytox" does a fine job of "breaking metal to metal contact", won't diesel, provides a corrosion barrier (even the "plain Jane" GPL205 I use), and it's designed to also work with "rubber seals". I do know that "molly paste" has been used successfully for airgun lubing over the years, however I found this "cut & paste" from a military manual to be interesting anyway.........


Anywhoo.....after using molly paste, "tar" & DriSlide for decades I nixed the "black stuff" a couple years ago preferring the Dupont "space station lubes".

What Ed said, I have been using Ultimox exclusively for several years....
