I'vr got the hammered finish pait from Jim Carter (even they don't know if I need a primer or not) and am getting ready to put it on the heater. Does anybody know which parts are painted black and which are painted in the hammered stuff?

I suspect the fan cage is to be black, and was planning on doing the inside in PPG single stage black so it will last longer. Any advice out there? What is the proper factory approximation?

Thanks!!!
