The thing is, and I think Denis knows this, is that there is likely some rust under the copper base plating. It should dome down to bare metal. A stiff wire wheel will get the stuff he can reach, but dipping or blasting will make sure.

There is a lot of debate about dipping things that are joined by spot welds, etc. It takes extraordinary effort to make sure the blind areas are neutralized. I knew of one restoration shop that refused to did anything but engine blocks and the like.

So that bracket could be a problem if not done right.
