Opinions needed:Paint or Powder Coat Drum brakes?

I've been looking at my rear drums and don't like what I see...Little rusty, and flaking...

Should I paint them the stock color? What is it anyway?
Powder coat them? Anyone done it?

If I do paint them... any heat issues I need to worry about?
Not many powder coaters on island...

Inputs/ideas wanted...

Mahalo!!
