What does rusting need?
For something to rust you need oxygen and water. Rust specifically relates to iron (or iron products such as steel); it is iron oxide. When the metal comes into contact with oxygen disolved in water the iron in the metal reacts with the oxygen disolved in the water to form iron oxide - rust. This is why most metals are protected, to stop water and oxygen getting into contact with the metal and causing corrosion i.e. rust. Common methods of protection include galvanising, painting and coating.
Can you stop iron rusting?
If there is no oxygen available, iron can not form iron oxide

How do you stop iron nails from rusting?
The most important solution is to use greases.
Can iron bars be painted in order to stop rust when concreted?
No, after painting iron can not make a strong bonding with concrete, the purpose of painting is the prevention of rusting but rusting process occurs in presence of carbon dioxide and moisture, when iron bars are sealed in concrete the rusting is not possible.
How can iron be treated to stop it from rusting?

How do Car manufacturers prevent rust in their cars?
they can apply paint to the iron or steel to stop the rusting of the car
How do you you stop iron rusting?
rust is iron oxide, this is FeO. To stop the addition of oxygen you must place a barrier in the way, the most cost effective way of doing this is to paint the metal.
Why doesn't a coat of paint stop the rusting process on iron?
paint won't stop rust, it only prevents it if apllied to clean metal.
What are the ways of preventing rusting?
Rusting is the oxidation of iron. To prevent rusting you must prevent oxygen from coming into contact with the product. This is normally acheived by applying a barrier of oil in working environments. Products are available for storing materials for long periods to avoid rusting. These have a more waxy nature than oil and would not be suitable to use to stop rusting in a mechaincal item. Of course if you want to prevent rusting and for it to look nice. various paints and lackers can be applied. Chemical coatings can also be applied to prevent rusting. Or simply keep the item clean and dry and rusting can be slowed.
