Response to 392 valve observation

while i am fairly new to the air gun community,as far as mods. and rebuilds,i have been a professional mechanic for 30+ years.in my years at the shop i have tried a wide variety of prelubes, assy.lubes,etc. i will agree that sylglyde is a great product with many uses. recently i have been using a silicone gel/electronic grade dielectric "grease" on an assortment of o rings,and the rubber/silicone gaskets{like the ones used in plastic intake manifolds} with good results.i am planning to mod one of my 1377s and intend to try this as an assy. lube,using only the thinnest schmear needed. when i get it finished, and run a couple tins down range, i will report back after a teardown,to inspect for any reactions in the seals, etc.
