Hi Greg, Yeah well it depends - there are fors and againsts. there are all the points that you mention, but there is also the fact that black surfaces have a higher emmissivity (radiate but also absorb more heat). but that effect may be offset by the fact you are putting a layer of paint over the surface actually doing the emitting (thus maybe insulating the surface).... there are also specially developed heat transfer paints available.
Andrew D or Andrew S (I think?!) discussed some of these intercooler painting advantages/disadvantages last time the topic came up, and also mentioned some testing he knew of, or was involved in, on the area. may be in the archives??
