Painting the Radiator

[NHCharger]

In the home stretch on the body work and paint on my 68. I plan on painting the engine bay and radiator support this weekend. I bought an aluminum radiator for the car. I'm going to need to paint this black also, correct?? Do I seal it and paint it like the rest of the car or is there a different approach? I saw a thread on this once but cannot find it.

OK. found one. Still leaves a few questions but I get the idea.
