You could use some steel wool, to get some of the rust off, then paint over tha area with rustoleum. That helps prevent rust, Hope this helps.Aluminum doesn`t rust. This is probably tin. If a magnet sticks to it, treat and paint as you would steel.Uh......... aluminum doesn\'t rust. Has to be some iron in there somewhere.Other related question
