Permanent Teflon Coating?

Thread starter #1
Is there any type of baked on, permanent coating for improving the slickness of small parts such as pivot pins?

My FIL has had several guns done with black T. I've shot a couple of the guns he's had it applied to and can't say that it improves anything as he's pretty ocd about maintaining his guns.

His EDC gun shows little wear on the cycling parts or normal holster wear areas. He did tell me that Mr. Birdsong (who died last year) said that he never advertised because he had enough work from govt contracts to keep him busy. His son took over after his death and at least has a website up now.

There's a ton of different finishes out there with good reviews but robars np3, black T and severns hard hat seem to have the best combo of wear and corrosion resistance.

I'm going to have a pistol green T'd later this year. I'll let you know how it turns out

Aren't all these products exterior finishes? I'm more interested in some type of ultra thin coating that could be used on internals. Specifically, I'm installing an oversized pivot pin through a trigger, and it will not normally be pulled out and lubricated. Firing pins would be similar - seldom removed and lubed.

Maybe the best alternatives for these items are the dry lubes?

Gear Kote is an internal coating. Used primarily on engine internals (cylinder walls, valve stems, cams, 2-stroke pistons, etc) and especially transmission gears to reduce friction and allow cooler running.
This company also has a baked-on product:

I've done several 2-stroke pistons and various parts. You can use a rechargable aerosol can to spray it on and an old toster oven to cure the finish. I am on the lookout for an old beater 1911 and will use both products for resinishing it.

I think Gun Kote is way more durable than "duracoat" finishes and Gear Kote can only be removed by bead blasting it. The "normal" product cures at around 300f for an hour if I remember right. The ceramic coatings need way higher temps, don't think you could do that in a garage sale tooster oven.

Do not use Mama's kitchen oven!

I found Gun Kote to be a bit brittle.. Cera Kote is the best home finish..IMHO

the bake on Cerakote you do at 200 for 2 hours. very thin .001 and very durable.

Many custom gunsmiths use CeraKote

There are several automotive products out there that get into the pores of the metal and lubricate. Though these are not finishes they are probably worth your consideration if you want to reduce friction. (z max $35 at Wal Mart) I have a friend who says hes showing promising results using it on rifles . He claims to be getting smoother operation, lower pressures, higher velocity and easier cleaning.
I had a tarus total titanium that came with case colored hammer trigger ejector rod etc. These parts were not low maintenance which was one of the primary considerations when making the purchase, I had bought it at Bernies when he was still in buisness. After several months of dealing with the case colored parts rusting at the drop of a hat, and at Bernies suggestion I had him send the parts to Birdsong to be coated with black T. Not only did they become maintenance free but super smooth as well. I think at the time it was about $ 85 to have the internals done.
I have used the Brownells oven cure moly teflon finish and it works great for external surfaces but the color will wear off on moving parts/ friction areas.The beauty of the moly teflon finish is just because the color wears off dosen't mean the moly which infuses into the metal is gone. Just be aware if you decide to use this product, that you are supposed to media blast prior to use for proper results.

I use Norrell's Teflon Moly but you have to beadblast the surface first. Not sure if that's what you want on a pivoting surface.

+1 on the Robar Mp3. I think its what you are looking for. IIRC, its teflon impregnated nickel plating.
This looks like it would definitely work, but it's not DIY. It would probably be worthwhile for a complete trigger group, but not one pivot pin. I may consider going that way.

Here's something else that looks promising. I sent them an email asking if it might work in my application:

By the way, I found the reference to RO59 at this site, which contains a wealth of expert information on coatings. The nickel/teflon coatings are mentioned in a number of threads as well as moly coatings: http://www.finishing.com/73/49.shtml

I've also sent Dow Corning an information request about MolyKote:
http://www.dowcorning.com/applications/search/products/details.aspx?prod=02412241&type=PROD

They also have a baked on version (MolyKote 106), but it's only available in $90+ containers. (http://www.dowcorning.com/applications/search/default.aspx?R=26EN)

It kind of goes against my grain to sandblast (or bead blast) a polished part so the coating will adhere. Does the Gear Kote fill in the pores to produce a smooth, polished finish?
