Now the big question, should I paint it black or leave it natural?

Nicer looking tanks than my fabbed Champion.
I shot a mist coat of zinc chromate followed by a thin coat of semi gloss black laquer on the bottom tank only of my aluminum rad, polished the top. For maximum efficiency left the fins natural rather than coat them with paint
 I like shiny, you may not

Great air up here, long hoses.

Here is the inside of the old vs new. The old is a 28 year old Checker Auto Parts purchase and it cooled just fine. I'm thinking the new should handle the the addition of A/C.

I painted the front of my griffin aluminum radiator flat black. I don’t care for the look of a shiny radiator showing through the Mustang’s grille.  But I do like the aluminum look under the hood.

Plus... Not painted does not peel or chip.

Yup, the last line got me "Any swap performed with lots of booze..."

For anyone thinking of painting their radiators remember: paint on the radiator will reduce the heat transfer. If you need to paint your radiator, use radiator paint (yes, there is such a thing). No primer, use as little paint as possible.
