I told him flat out he is not getting into my supply. He found some somehow. It is not like it is illegal to have. I have had a few folks give me a can that was in their garage and they will never need it.
I would never use air to purge the system. I have a nitrogen bottle for a static pressure test or to purge after the system is opened to air.
