I wasn't planning on doing anything with the paint/patina, but a tested a light scuffing with a scotchpad. In no time, I did half the hood.
I'm amazed at how much 'crud' came off. I'll be searching around to see what others have been doing with the patina, but I think I'm going to try lighly polishing it, I just don't want to remove what little paint is left lol
