I see that compressors for PCPs have moisture traps to avoid sending corrosive, damp air to the tanks. I live in a hot, humid, salty (coastal) air environment - the 'perfect storm' for corrosion - and wondered if anyone has seen any studies or had experience concerning this issue in the pressure chambers of springers. Each shot expels the stuff, obviously, but at the end of the day when the gun is put away it has an unpressurized "tank" of that air remaining in it. It's a constant battle keeping the rust away from the outside of the gun, but what happens inside?
