I agree with that statement. Actually the more pure water is the more corrosive it becomes. We run in to this quite often in the commercial HVAC industry. The water removed from air in an air handler is pure and loves to eat steel condenser pans.

Not so actually. Corrosion reactions are often limited by the conductivity of the electrolyte, which tends to increase with the amount of ions in solution. Corrosion is an electrochemical process... not at all like dissolving some salt in water.

P Glycol is a mild corrosive on it's own. Been using pure p glycol in di water with an off-the shelf tranny radiator for many years however. I would recommend an inhibitor if it was certified food grade etc. Have not done the research, but I'd bet the ones sold by micromatic etc are good to go.
