the bar-b-que black does not need a primer when used on aluminum cookers. Worked great on mine. Brass sheet has very little porosity, and what porosity it has is very fine. That doesn't provide the "tooth" needed for paint adhesion.
Keep your steam up!

With my elf duties done, I cleared the oven to make way for the turkey. And I am glad to report that the paint job turned out great! Nothing bad happened to the brass. The baking process gives it that commercial look and feel. Thanks!
Merry Christmas and Happy Holidays, Joe

Okay, now we are cooking. We are baking the painted brass for four hours at 250 degrees on a pizza stone (upside down). We are using Rustoleum Satin Cinnamon to approximate the wood look on the Lion. I could not find the color in a spray which would have made the process easier. We used the Radio Shack Etchant Solution and the Rustoleum Clean Metal Primer to prepare the work for the color application.
Merry Christmas, Joe

The only thing you have to worry about when heating the brass is to make sure you heat it evenly. An oven or regular steaming of the loco will do this. Heating the brass sheet with a torch will not, and the metal will warp.
I routinely use .005" brass sheet on my locos, and have never had an ounce of trouble with them warping. I use them for boiler jacket material, and as a wrapper around the smokebox. You'll be fine.
One word of caution: I recently tried Krylon's bar-b-que paint, which they advertise doesn't need primer. Don't believe it for a minute. The paint flaked away with only the slightest provocation. I took all of that off, and repainted with regular primer, then a coat of regular black paint, as I've done on my other locos without problem. That worked far, far better.
Lesson: Stick with what works.
Later,
