Hi all. I picked this up about a year ago and it's slowly been getting rust spots for a while now. I'm about to sand it all off but before I do, I just wanted to know how I can prevent it from just rusting all over again? Now I'm a woodworker so I don't know metal but would polyurethane or lacquer work? I don’t want to paint it if I can avoid it. Any advice would be much appreciated! Thanks very much.
