Powder coating is amazingly easy. We are limited to what fits in an electric oven he had leftover from his old house.
The bronze hammered Rustoleum looks pretty close in color to what I've seen of the bronze Hammerite. If I was doing suspension parts or anything exposed to the elements, I'd worry about the difference in durability but for the heater it should work just fine.
I also lightly blasted the end caps of the core and left it to soak in kerosene. I'll shoot it in high temp black after flushing it out.
