Painting over rust can jeopardize the metal surface's structural integrity and cause the paint to flake or peel off. Rust is a sign of corrosion, which can weaken and deteriorate metal surfaces over time. Painting over rust does not address the root problem—it just covers it up.
Paint alone does not adhere as well to rust and when it does stick, rust stains can bleed through the paint coat and discolor it. Typically for rust, you do not want to use a latex (water based) paint because it may cause the metal to rust more and will bleed through and stain the paint.
