I have recently been restoring a 1950's home with a double fireplace and have restored the brass fireplace doors to the best of my ability but am not all to thrilled about the results. Is there a way for me to paint them to give them similar look of powder coating without the expense ? How would I prep the surface and would a high heat Automotive or Grill paint look good. I am only looking at doing th exterior surfaces. I am wanting a flat matte black look.

Thanks
