Rust creeps under paint. If you see a spot of rust, chances are it's under the paint already in the surrounding area. It's one of the main reasons for etch primer. When we sand through to metal on anything, we etch it. Sealer is enough, but the etch primer will stop the rust creep under the paint. Touching up rusty chips, just slows it down
