What a product will or wont do totally depends on the condition of the machine. I think many people think that every vintage machine can be shined up like new. That is not the reality.
This. The shellac clear coat used to protect the decals on old black machines is often in poor condition. Rubbing wax on the machine can rub the old shellac and decals off if you're not careful about what you're doing.
I would think almost any decent automotive wax would work well on machines that can handle it.
