According to Eezox, water is heavier than oil and will sink through it to the surface of the metal which can cause rust. That's why oil floats on water and not the other way around.
EEZOX® weighs 10.42 pounds per gallon - squirt or spray EEZOX® into a container of water and it will sink to the bottom. This density prevents water from penetrating the thin layer of EEZOX® and from reacting with the metal to form rust. Because of the hydrocarbon oil content of other products, they will "float" on water. Therefore, water penetrates this oil layer and rests on the metal surface. The water then reacts with oxygen and the metal surface to form rust.
