Crawl space doors tend to rust at the bottom as water gets caught in a track that holds the door. If you do not remove the rust and protect it with paint it will deteriorate to a point where it needs to be replaced. To prevent costly repairs and having to buy a new crawl space door remove the existing rust with sandpaper then paint it with Rust-Oleum premium oil-based protective enamel. This will ensure that you get years out of your crawl space door and save time and money down the road.
