Paul is right on. Listen up Dave.
The tar based paint used at all radiator shops has a purpose.
It allows much greater heat transfer to the air than lacquer or
enamel. You can get away with hardware store paints on the
upper tank for appearance but NEVER paint the core. Asking for
trouble.
Even the radiator shop paint is applied mostly to the tanks and
frame. They typically hit the core as lightly as possible for
appearance sake. The best heat transfer is from bare copper!
Eastwood has been selling a proper radiator paint now for about
two years. That is the home hobbyist answer.
