Yea, very wrong.
Oxidation process of loss of electrons, typically it is the formation of an oxide: rust better know as Iron Oxide. There is no hydrogen molecules. Incidentally molecules are composed of atoms...
Bolts in an Al car engine rust quickly? New one to me.
Steel is an alloy of many atoms, Stainless contains Chrome, which forms Chrome Oxide, which passivates the surface, inhibiting the oxidation of the Iron.
Really.. really wrong. I am not even a metallurgist.

I may be wrong, but I believe in at least some of the cases the problem isn't moisture, it's a issue of dis-similiar metal corroson. Which is what happens when certain metals come in contact with another metal. They aren't compatible on a molecular level and as a result, one of the metals loses hydrogen molecules. Which, is what is known as "oxidation" and the physical, visible result is corrosion or "rust".
I believe it's something to do with alkaloids/alkaline content of the various metals. That's why the bolts in a aluminum car engine will rust quickly. The bolts are steel, the engine is aluminum, the heat of the engine accelerates the process.
Stainless steel is more resilient, because it is an alloy composed of various types of metals, not one single type of steel.
