Default Duct Rust

I have a cold air register for my oil furnace in the front hall. Living on the east coast and getting a lot of snow, a lot of water gets through the register from leaning wet shovels against the wall and walking on the register with snowy boots on. Recently I started hearing a banging noise down cellar. One suggestion on this forum was it was caused by the ducting cooling off when the furnace shut off. I just realized that the ducting leading down cellar from the front hall register, from years of moisture running down it, had rust on it and a small hole had developed. Anybody know a way to patch the hole and get rid of the rust? Thanks

If you have access from below your best bet would be just to repace it.

If the rust isn't too extensive, and the hole is just a small one, try the following: Wire-brush the surface rust off, then hit it with some zinc-rich spray paint. After the paint is dry, install a surface patch of galvanized sheet metal, using sheet metal screws and a sealant under the metal.
