SM50 --what do you use it for?

[Hsing-ee]

I only really use it for leather breech seals.
What do you use it for?

The smell reminds me of late 1970s springer ‘tunes’ .. it’s the olfactory equivalent of an Echo & The Bunnymen song.

In terms of actual airgun use it’s the best thing to lubricate a leather washer with, containing silicone for the leather and molybdenum for the metal. As such there’s not much call for it for modern rifles but for pre-1980 it’s a must-have.
