Metal comes in contact with oxygen. That's the main reason that many mechanics wipe down their older metal tools with oil (WD-40). The coat of oil prevents air from contacting the metal. That's why they spend much more than $100,000 to paint a bridge. The coat of paint saves them. H2O, water, has the same effect on metal.
