1970 Chevelle Radiator Paint Color?
 

I have a quick question regarding paint color for a 1970 Chevelle radiator.
I am restoring my radiator and it is ready for paint. My question is should it be "gloss" or "semi/satin gloss"?
I should already know the answer but I'm not 100% sure and everything I see in post it goes either way.
Thanks in advance for the help.

I restore all of our cars with a high temp glass black.

Thanks Rick. Was leaning toward gloss but wasn't 100% sure.
