Muzzle Threads Anti-Seize Compound

[popgun pete]

I am wondering if any of the Italian forum members can find out what the anti-seize compound was that was formerly used on the screw threads of pneumatic spearguns. It was a thin, white coloured and wet looking material, with a slight blue tinge, relatively easy to wipe off the screw threads and not like a grease as such. I saw it on pneumatic guns from the late sixties and early seventies, but I don't remember seeing it on the Spanish models. This stuff was on guns that had never been dismantled and were as originally assembled by the factory, often including a few pieces of metal that were screw thread turnings left inside the gun, but fortunately trapped in a location where they did no harm. Only someone from the old days at the factory will probably know what this compound was, but they will certainly know what I am talking about as once you saw this stuff you could not mistake it for anything else. I always wiped it off during parts pre-assembly cleaning, but later replaced it with grease, particularly after I had a "Sten" muzzle seize up without using any grease on the screw threads.

What do you think about using neoprene glue? I read somewhere somebody were using it for vacuum barrel sealing. I did not try it.

I think that any form of glue would only add to problems, you want something that stays soft, but does not leach out of the gap between the screw threads. Oil does not stay put over time, so you need something else. I was wondering if the compound had zinc in it, hence the white appearance.

white stuff sounds like lithium grease. You could also try copper grease or a marine grease like quicksilver 24c. Vaseline is also used as is siliicone grease etc.

It was not lithium base grease, in fact I have used lithium base grease on pneumatic guns ever since I had the muzzle seize on the "Sten" (Valvoline X-ALL). The stuff was somewhat like oil in consistency, but was distinct from the lubricating oil used in those guns. The purpose of this thread is to find out what it was. Modern pneumatic guns seem to use silicone grease.
