Metal needs two things to rust: oxygen and moisture (water or water vapour in the atmosphere). Rust on iron is a mixture of various iron hydroxides, not just iron oxide.

If you emerge certain metals in water for very long periods of time they will eventually rust when they are exposed to the air again you will notice the rust.

100% o2. Highly corrosive.
Oxygen is what causes most metals on Earth to rust. A scientific name for rusting is oxization.

rust is Iron Oxide , Fi03. You need Iron and Oxygen.
If you wanted to speed the process up you need to increace the surface area through abrasion or corrosion.....Salt water seems to do horrible things to unprotected trailers..maybe try that.
