How do you prevent rust?

To prevent rusting you can put on a rust converter then paint it with a epoxy type paint designs for metal and wet conditions. How cool is that!!!

Either put it in a moisture free zone (coz air and water cause rusting), cover it in oil, use galvanizing, or sacrificial protection.

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.
You should keep metal dry, or add a coat of paint laquer, or wax. You should prevent oxygen from coming in contact with the metal, and spray the metal with water repellant
Well an Iron nail needs moisture n oxygen doesn't it to rust, so to stop it rusting (or oxidising) which is what's actually happening, you could cover it in wax, store it in acid or a vaccum. Either way, anything that keeps it dry n oxygen free
So at school in science this term we are trying to do what you are trying to do. We are still in the middle of observing the iron nails but what i am using is:

• Vaseline
• nail polish -yeah, i know right!!!
• Sacraficial metal (you wrap it around the iron nail)

The way that is working the best at the moment is actually the nail polish!!!!

Hope ive helped :D
