You can buy it in a spray can at an auto supply store. I've worked with metals for years. After you polish it handle it with a rag rather than your hands or use gloves. The oils on your hands will leave an invisible mark that will show up later UNDER the clear coat. If that happens you would have to strip the clear coat off and redo. Also, don't apply it too thick or it will discolor. Two or three thin coats works better. The smell is noxious so do this project outside.
The downside of the lacquer is that it will eventually chip and tarnish in the chipped areas only. It's impossible to get a nice polish where it chips and would have to be stripped with acetone and redone.
