Interesting. Searching on google reveals that astronomers are super-interested in light-absorbing black treatments -- to reduce stray reflections in their telescopes. All the amatuer guys seem to swear by this "Nextel Black Velvet" paint which 3M used to make and now appears to be in the hands of this German company:

Company : Mackiewicz GmbH in Hamburg, Germany
Telefon : +49-40-751030; Fax:+49-40-75103375
Lack : 81121,Nextel Velvet, Schwarz (black),1kg 5kg 25kg
Thinner : 8061, Nextel Thinner

It also seems to be just as absorbant in the near-IR range as it is in the visible range while something like black-anodized aluminum is super-reflective in the near IR.

But, I have not been able to find out via google if this Nextel paint is good for exterior use or if it is interior only.

Now, I'm also wondering about carbon-fibre construction - can you mix weird stuff like paint or some kind of powder into the carbon fibre when it is molded? Or at least paint it afterwards without as much fuss as it takes to paint our regular cladding? I'm thinking that if those guys who are talking about CF replacement cladding can make the parts super-duper-permanent black, that would be a plus too, no more having to worry about treating the cladding to keep it looking black.
