Figured I should update this with a picture.
2 dips in high test vinegar to get the rust, a coat of rust converter, and 2 coats of black semi gloss. Can’t say they’re good as new because of the rust pitting but look damn good now.
the actual hangers are new parts and need a coat of paint themselves before install. New parts never seem to be up to my standard. Still need correct sized bolts as well.
