Anybody use this "no-rosion" coolant additive? A respected early T-Bird (excuse me) mechanic, "Gil's Garage", and many collector car owners use this. Can be used with just water in places, such as where I live in the South, where you don't need freeze protection, said to give better heat transfer, lower coolant temps and give excellent corrosion protection or with antifreeze, said to protect against corrosion long term.
