Nor do metals form acidic substances based on carbon, or substances that coat their surface to protect them from rust and oxidation.
According to the best science available, rust and oxidation is a natural process caused by a chemical reaction between oxygen or other chemical which tends to corrode a metal.
There has never been any metal known to have DNA or other organic acids that produce any anti-oxidizing substance which coats it's surface.
Can you show some examples to the contrary?
