I must respectfully, but strenuously disagree. The space shuttle was also given as an example, and there is no secondary fluid behind its black tiles.
Click here for more info. (You'll notice there is no mention of secondary fluids anywhere in the description.) Furthermore, silver & white surfaces are poor heat emitters and therefore exactly what you
don't want when in a situation the OP describes.
