I thought the black radiator paint used by good shops was a special formulation asphaltic based stuff. Designed for flexibility so as not to flake on expansion and a special pigment that conducts heat well--much better than leaving a core bare which would invite corrosion. As mentioned, ordinary paint blocks heat transfer and is too hard but this stuff supposedly is just the opposite. While it appears thick, claims are there is actually more surface area to radiate. Is this not the case?
