painting radiator

Well I just cleaned my 3 row rad and its ready for high temp paint.Is it good or bad to paint the fins and coolant tubs.I have in the past and always thought that maybe the paint is keeping the heat for geting out some.never had any issues of overheating this is just a thought.What have you guys or gals done pain or not :cheers:PS why is the top tank bigger than the bottom.
