Because oxygen can still pass through rust.
This is lot the case of all metallic oxydes. Many if them prevent oxygen from passing.
To repair rust damage, start by sanding down the affected area to remove the rust. Next, apply a rust converter to stop further corrosion. Finally, use a primer and paint to seal and protect the metal surface.
Washing doesn't stop rust to return.
To stop rust after sandblasting to bare steel, you can apply a primer specifically designed to prevent rust, such as a zinc-rich primer or an epoxy primer. Make sure the primer is applied evenly and thoroughly to create a protective barrier on the exposed steel surface. Topcoat the primer with a high-quality paint to provide an additional layer of protection against moisture and corrosion.
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.
Yes, rust can cause a piece of metal to stop working properly by corroding and weakening it over time. Rust is a form of oxidation that occurs when iron and oxygen react with moisture in the air, leading to the formation of iron oxide. If left untreated, rust can eventually render the metal unusable.
The best rust solution for metal is a rust converter or rust inhibitor that can stop the rusting process and protect the metal from further corrosion.

Yes, painting over rust can temporarily stop its progression by preventing oxygen and moisture from reaching the metal surface. However, it is not a permanent solution as the rust may continue to spread underneath the paint. It is recommended to properly remove the rust before painting to prevent further corrosion.

Look for an anti rust spray.
Rust is stopped by preventing oxygen from getting to the metal. This is often done with a coat of paint. Oil and grease can prevent it. Some metals are coated with a thin coat of a metal that doesn't rust, such as galvanized steel.
no it can not
Uranium
to stop rust you must stop the oxygen having acces to the metal, this can be obtained by using a non rust paint or just covering the metal with a few layers of regular paint. it is also important to aavoid letting water near to a metal with no protection as this is how rust starts to occur :)
They don't remove the rust, they treat it, seal it and stop it from continuing on.
the best way to stop surface rust is to sand the spot of rust off and then spray it with some primer to keep the rust from coming back
