I stand corrected. However, Forespar has this to say about their own brand, Marelube:
MareLube Valve™ has been refined by Forespar to suit the needs of boaters for the lubrication of marine valves and seacocks of any material, metal or composite. Very importantly, MareLube is not petroleum based so it will not degrade seals and O rings. All marine valves require regular lubrication and regular activation of the handle. MareLube operates over a wide temperature range from Tropical to Arctic conditions. Apply liberally to valves seals, balls and any other moving parts. I'm sticking with my PTFE grease just in case.
