I'll be following this thread because I just received my ACP aluminum radiator today. I was planning to wipe the aluminum down with alcohol and then use Dupli-Color engine enamel primer with ceramic that withstands heat up to 500*F. Planning to finish coat it with Eastwood Radiator Gloss Black. I plan to shoot a test piece of aluminum tomorrow to make sure the paints are compatible.
I'm leaning towards painting the top, sides and bottom, but not the fins. I have an A/C condenser in front of the radiator and the back has a shroud and thermostatic clutch with a 6 blade fan. I don't think you can see much of the fins, but I will set it in place to look before making a final decision. My setup attempts to keep everything under the hood looking OEM so I don't want the aluminum to be noticeable.
