Keeping an outdoor table dry and covered from the elements will help keep it from rusting. Paste wax, greasing, and rust-proof paint are other ways to keep them from rusting if you're unable to keep them out of the rain.
Keep it away from water and away from the sun
Most car radiators are made of aluminum or a combination of aluminum and plastic, which are not susceptible to rusting like iron or steel. Additionally, the cooling system in cars is filled with coolant that contains corrosion inhibitors to protect the radiator and other components from rusting. Regular maintenance, such as flushing and replacing the coolant, also helps prevent rusting.
Coke cans or many other canned beverages are housed in cans made primarily of aluminum. As aluminum is remarkable for its ability to resist to corrosion or rusting (due to the phenomenon of passivation) and its low density, the rusting process is extremely long. Additionally, corrosion resistance can be excellent due to a thin surface layer of aluminum oxide that forms when the metal is exposed to air, effectively preventing further oxidation. This corrosion resistance is also often greatly reduced when many aqueous salts are present in the environment however. Hence rusting is generally only feasible when a can has been exposed to a wet and harsh environment for extended periods of time.
Aluminium doesn't rust, ever. But it can corrode, which is similar. Anodising offers some protection, but it's all down to how bad the environment is. Bad enough, and any metal will take damage.
Not rusting of aluminium; a protective layer of aluminium oxide is formed.
Aluminum does not rust like iron does. Instead, it forms a thin layer of aluminum oxide on its surface which protects it from further corrosion. This layer acts as a barrier, preventing the metal from rusting.
Under most conditions aluminum will not rust in water. However, if the aluminum is alloyed with another metal, oxidation (rusting) could take place.

Paint it
Yes aluminum furniture does carry the risk of rusting with it but it also can absolutely be treated with an antirust product so you don't have to worry about it.
In order for you to keep your iron pot from rusting, you will need to keep it away from any water or moisture. I have also found that coating the iron, such as a seal or paint will dramatically limit the amount of rusting.
To keep the tip from rusting.
yes i have coating to put inside a 3200 gal water tank to keep it from rusting
Aluminum does not rust as iron does. When exposed to air, aluminum forms a thin layer of aluminum oxide, which acts as a protective barrier against corrosion and prevents further rusting.
No. generally speaking your engine block, heads and intake will be a coated cast iron or cast aluminum. Neither will rust. Also keep in mind that oil from both your vehicle and the road are coating the exterior of your engine while you drive. If you are worried about your exhaust manifold rusting you can purchase header wrap or paint them with high temp paint.
It is important to put your battery far away from moisture to prevent it from rusting.
