Forum Title: Rusted Flashing
I have some flashing that is rusting from the salt air. Would you recommend sanding the rust off and then covering the flashing with Rust-Oleum, or should I just replace the flashing entirely?

I would go with a replacement. If it is salt damage, it tends to be too hard to get off entirely and the second round of damage is usually worse. Salt + rust = a mess that only grows. Just my experience with bikes, cars, and metal buildings.

I was afraid you'd say that. I didn't want to have to go get new flashing but suspected I might have to. It's so hard to keep anything metal in good shape here.

I agree with Tomtom, not replacing this rusted flashing will only cause the rust to get worse. The best thing you can do is to cut out the old metal flashing and replace it with newer galvanized metal flashing. This newer type of flashing has a protective coating that will prevent the steel core from rusting.
