Question

Can we permanently prevent the rusting of an iron article by applying a layer of paint on its surface?

Answer 1

No, we cannot permanently prevent the rusting of an iron article by applying only a layer of paint on its surface. The paint provides a protective coating and prevents iron from coming in contact with air and moisture, which are necessary for rusting. However, if the paint layer gets damaged or wears off, the exposed iron surface can come in contact with air and moisture and start rusting again.
