True! Powdercoat is placed in an oven to melt the powder which flows and fuses into a continuous hard, non-porous coating. While paint is appplied differently, it is never put in an oven, but if you paint it to thick then it creates a thermal barrier on metal. A friend painted a radiator back in 1990 with single stage paint in based on the body color, and I never had any problems with overheating.

Now, Dewitts has developed a new coating called Black Ice and the coating is formulated to give you the black look of original radiator, without the problem of heat transfer with traditional paint. http://www.dewitts.com/products/blackice
