I know this question has been asked before;

82 240D, Rust underneath the doors and behind the corners on the front fender, where the bumper is screwed on.

How do I treat it? I've got a can of bondo and a bottle of rust remover. I want to at least slow this S*** down before it makes the car look like a complete wreck.

I used the search but I got page upon page of unrelated info.
