rust , or the result of even surprisingly brief or prolonged exposure of iron to moisture,and the combining of waters oxygen molecules with the iron,resulting in iron oxide or rust,is a major problem for auto restorations, it can be prevented, or at least reduced significantly by use of a sacrificial barrier like hot dip galvanization or use of a exclusion barrier like paint or wax that prevents moisture contacting the iron surface.
if a part is exposed to direct contact with moisture it will tend to rust, anyone who has ever had an engine block completely de-greased will tell you a dust like surface rust will form in minutes, if the completely de-greased surface is exposed to even moisture in the air., so a short term barrier like WD40 sprayed over the surface will tend to slow the rust formation.

RÂust is the common name for a very common compound, iron oxide. Iron oxide, the chemical Fe2O3, is common because iron combines very readily with oxygen -- so readily, in fact, that pure iron is only rarely found in nature. Iron (or steel) rusting is an example of corrosion -- an electrochemical process involving an anode (a piece of metal that readily gives up electrons), an electrolyte (a liquid that helps electrons move) and a cathode (a piece of metal that readily accepts electrons). When a piece of metal corrodes, the electrolyte helps provide oxygen to the anode. As oxygen combines with the metal, electrons are liberated. When they flow through the electrolyte to the cathode, the metal of the anode disappears, swept away by the electrical flow or converted into metal cations in a form such as rust.

ÂFor iron to become iron oxide, three things are required: iron, water and oxygen. Here's what happens when the three get together:
When a drop of water hits an iron object, two things begin to happen almost immediately. First, the water, a good electrolyte, combines with carbon dioxide in the air to form a weak carbonic acid, an even better electrolyte. As the acid is formed and the iron dissolved, some of the water will begin to break down into its component pieces -- hydrogen and oxygen. The free oxygen and dissolved iron bond into iron oxide, in the process freeing electrons. The electrons liberated from the anode portion of the iron flow to the cathode, which may be a piece of a metal less electrically reactive than iron, or another point on the piece of iron itself.
The chemical compounds found in liquids like acid rain, seawater and the salt-loaded spray from snow-belt roads make them better electrolytes than pure water, allowing their presence to speed the process of rusting on iron and other forms of corrosion on other metals
one the best forms of protection is a two layer barrier, of a good rust/moisture barrier paint over an inner rust preventive coating like galvanization, but each product has its use limitations and strong points

ust Prevention for Cars and Trucks (a practical guide to prevention)
Let’s face it, nobody likes rust on their car or truck. However, rust is an almost inevitable reality for cars in many areas. In some states, the saltwater in the air promotes rust. In other states the salt applied to the roads is the biggest factor. If that wasn’t enough, the high humidity and heat in other areas is to blame. Under these conditions it is no wonder that we spend so much time fixing rust on our cars and trucks. Clearly avoiding rust in the first place is going to save time on and money in the long term.
We’ve compiled a few common tips that will help you prevent rust from forming on your vehicle.
* Keep your car clean
* Wash the underside of your car or use automatic washers with underside spray. This is most important during the winter when salt is applied to the roads.
* Wax the body of your car
* Keep the proper coolant ratio in your car. Using too much water in your radiator increases the chances of corrosion in your cooling system.
* Use a car cover that breaths so moisture from the ground isn’t trapped under your car.
* Fix chips in your paint before your car or truck has a chance to rust.
* Remove mud and other debris from your wheels and wheel wells.
* Make sure your drain holes in your car are free of obstructions. This is a major cause of rusted doors.
