Bit late to the thread but UK bound folks might find this link useful, it seems to be the right stuff

So, having read of the thread, what I want to do in the event of a total rebuild is to take everything out of my gearbox, wipe the box and gears down, polish the piston rails, then give the inside of the box a spray and then the gears a liberal coating then reassemble everything then not worry about needing to grease my gears for the next 6 months?

That looks to be the correct sort of stuff.

You really need to do more prep than just wiping down your gears/piston/g-box shells.

They should be thouroughly degreased to give the best results, and heated slightly before application and a bit more after.

Two or three very thin coats is best, rather than one thick one, with some heating in between (with a heat gun, just enough to dry the film out fully).

Then when it's fully cured (around 10-15 minutes usually, check the spec) you can polish the mating parts (rails on piston and g-box, gear teeth, tappet plate tracks, etc) with a fibre brush in a Dremel.

Molykote is the one I use but the other is probably the same formulation.

 

Whatever you get, read the safety precautions and follow them to the letter.

The latest stuff is much safer than the old ones, they were extremely carcinogenic (among other things). :unsure:

Yeah, they sell the birchwood Casey stuff at my local gun store. If I had had the patience I would have done it in my M249 I was working on, but once the parts came in.... I couldn't help but get it back together asap.
