Hi everyone! I recently bought an orange truck bed trailer that I think came from a Plymouth arrow sport from between 1978 and 1980. It’s got a lot of rust which has made some pretty big holes in the bed so I’m mostly looking for advice on patching the bed while keeping the original appearance as intact as possible. It’s such a cool color/design and I don’t want to spend a lot fixing it up, so I’m just clear coating the outside despite the rust spots, but the bed needs some repair.

Any advice would be appreciated. Thanks!!
