That stuff was invented in 1943 for keeping moisture out of airplanes!!! It's not intended as a lubricant but will work okay as one, it's for electrical insulation from moisture.
Dimethyl silicone compounds should not be applied to O rings or other components made of silicone rubber because they will destroy the silicone rubber. These compounds will also slightly swell natural butyl rubbers.
It won't work for lubricating your piston head o-rings, your GBB mags, or valves, or anything like that. Put it on gears and only gears.
