moly grease

You want the paste not the grease, that stuff will migrate all over the place and make a mess. If you have a Honda motorcycle store of maybe even a dealership they sell paste and its 70%. You hardly need any, just enough to take the sheen off is enough
 
Jet Lube MP50 paste.

Used it sparingly.

Thanks guys. I kind of figured the stuff at Canada Tire was not the stuff to use but the price sure seemed nice, lol.

Edit--I ordered some of the Jet Lube from Graingers. Thanks HuskyDude!

I just went through this myself there are a few widely available options the jetlube mp50 is 50% moly loctite 8012 is 60+ %moly but both are pretty pricy and a little goes a long way i ended up settling on Lloyds laboratories ms2 moly paste its 66%moly by weight ( I called the manufacturer to confirm) and it cost 13 bucks for 8 oz can
 
If it works for you that's all that matters.
But remember Loctite 8012 and Lloyds Lab ms 2 are both considered Anti-seize Lubricants.
Where the Jet-lube MP 50 is just a lubricating compound.
If you want to compare a Jet-lube product they make a variety of the Anti-seize/Never-seize in different pastes.

Again, used it sparingly.
 
I did a bunch of research, the antisieze designation threw me too but if you look at the specs and applications, content etc it looks like its just a marketing decision but I could be wrong . The ms2 paste seems to be working well in my gun I went with the ms2 over jetlube mp50 for the higher moly content and synthetic based carrier that is rated for higher temp with the thought that it may reduce the possibility of detonation and it has been good in that regard a little smoke on the first few shots but no loud noises or erratic velocity spikes so it seems to be working out in that regard

I've never used moly grease in any of my airguns. The moly particles act as an abrasive on the rubber or synthetic piston seals. Good for metal on metal, not so good for seals.
A thin film of Lucas X-Tra Heavy Duty synthetic grease works very well for me.

That is interesting ... makes sense but i wonder how much moly ends up on the piston seal when applied properly? I basically smear a tiny amount around the piston behind the seal and then wipe it mostly off , if all goes well that part never touches the cylinder walls unless there is a catastrophic seal failure in which case it "may" help prevent scoring of the cylinder wall. The only other place i use it inside the cylinder is the back of the piston especially on the top and again very light application barely visible , it does make a difference in cocking smoothness but I dont think its enough to work its way into the seal and probably not enough to damage the seal if it did? Even so I can stand to replace a piston seal now and then if the metal parts aren't gouged and galled beyond repair. I really hadnt thought of the moly being rough on seals before I just used it the way it was recomended to me on metal to metal and potential metal on metal applications VERY sparingly it has smoothed out the cocking on the gun i used it one 100% but I havent fired 1000s of pellets through it yet.
 
Not all moly grease is the same. The products with a high moly content of small size moly particles is commonly used in, and recommended for, airguns. Moly should always be used sparingly.
Advice to never use moly is unsupported by the airgun industry, including the manufacturers of well-known tuning kits such as Maccari.
 
I have polished the trigger assembly to the most shine on my FX Impact and lube it with a thin layer of moly grease.
No other moving parts (hammer, springs, valve springs) gets any lube because that would "slow down" and may create timing inconsistencies when the elements changing along the year...all moving parts shall be dry dry.
The best moly ratio in a grease you can get from a Honda service, I don't think they sell it at parts counter but I asked the service manager if he could help me out. It wasn't cheap years ago.
