Someone advised me about my heater-box:
"If you want to be factory correct, buy the cheapest spray paint you can find and spray it blindfolded. :-)"

But I'm not going to do quite that :) I'd like to use a quality high-heat glossy black paint. Auto stores have various engine paint, and I've seen posts about farm equipment paint. Looking to narrow the field to a brand you all trust. I will first have bead-blasted and primed it. (primer of choice?)

I'm interested in your thoughts.

Thanks!
