I would definitely suggest a Kilz product. It works great for covering up water stains and preventing mold. We've used it to make painting over wallpaper a cinch. Don't see why it wouldn't work for rust. Though I would use it in a ventilated place because it stinks.

"I believe that when we leave a place a part of it goes with us and part of us remains. Go anywhere in these halls, when it is quiet and just listen. After a while you will hear the echoes of all of our conversations, every thought and word we've exchanged. Long after we are gone, our voices will linger in these walls for as long as this place remains. But I will admit that the part of me that is going will very much miss the part of you that is staying."
