This is a MUST for anyone who uses much paint. With the cost of paint unbelievably high, this will save you $$$$$$. It is a MUST for POR15 or other urethane paints that harden in partially used cans very quickly.

CO2 is very inert and can be used on auto paints. The oxygen is tied up so is not active. Only danger is forming carbonic acid in the presence of water so I wouldn't use it for latex paint but then that stuff doesn't skim like oil and urethanes so inert blanket on them isn't critical.
