Thoughts on using moly instead of tar on spring in Vortek Kit

[lefteyeshot]

Any one try coating a spring in truck bed liner ? ... ok i have a hatsan 125 .25 in need of a tear down , ill get back to you

Are you talking about something that dries like rubber, not paint. If so experimenting with an old B3 before and after might be worth the trouble. I've wonder if a spring had something like wire insulation on it what would happen.

  The black tar grease is applied sparingly to the spring with light stringing between the coils . The purpose is to dampen the spring oscillations during the shot cycle. The sleeve and tight spring guide in the Vortek kit do the same job

Thanks for all of the input guys!  I think I might try out a light coat of moly on the spring, just to see how it works out.  If I notice any buzz (which I can't imaging given the inner and outer guides), I'll go back to the tar.

Thanks!

Some folks also used a light coat of white lithium grease on them and reported good results.  Other than being cheaper, no idea if long term results would be comparable to tar (or moly)...

Good luck with the alternative(s), maybe break it back down after 5-10,000 rounds and see how it did (would be very informative)

I have been on the lookout for something comparable to the yellowish tacky grease Vortek uses.  It seems stickier than NLGI 2 and doesn't tend to fling as much as the Euro tar.  They wouldn't tell me anything other than Teflon based synthetic.  I did find that John Deere offers tubes of a non-tox Teflon base synthetic and is odorless , will not run drip etc.  As seen here, on my last trip to the dealer tried to get some but they didn't carry it.  I am going to order some and see what it does,

Plain Jane Krytox is Dupont's liquefied Teflon...

Only a few factors to consider no matter what gets used, will it stay, what's the additive(s) effect, and after 10,000+ shots or 20 years what is left of it and did it have any detrimental effects on the gun.   I know Krytox has been around a long time but I don't think anyone has just stuck it in there and peeked under the hood after 10 or 20 years so I tend to shy away from it for that reason, and only that reason (otherwise Ed has done some trail blazing and very well detailed work with it that I believe in time will become the gold standard --- thank you for that Ed!).

BTW, they do make Krytox with a "high pressure" additive.  Guess what that is?  Moly.  Fortifies my belief that Moly is more appropriate where high load exists, especially in the presence of higher temperatures (cocking, and end of shot cycle gas compression).

Everyone has a different opinion on this, this one's just my $.02 worth - maybe a lot less

FWIW I have been using synthetic lubricants in one form or another for over 40 years and most of the toys that I used it in or on were used and abused extensively so I tend to trust the synthetic lubes

White lithium grease worked well on my BSA Polaris.

Jason,

I would assume that this stuff would work well too,

I seen that one too, probably work ok who knows, but probably wouldn't taste as good.....lol......the rifles I have done with the Vortek lubes are real easy to clean up when you tear them down, if that really means anything, the tars and moly's seem to take more effort.  I think for the most part if you have a real good piston seal, most of your lube "should" stay behind them.  But different styles of seals may migrate more lube past.
