Gerry,
Many years ago we were building a composite canard microlight. The US
manufacturer had seom plots of different surfaces' emissivity (=absorption
coefficient) across a broad spectrum. It was almost down in the matt black
area. IOW very poor for heat reflection characteristics. I was very
surprised but I believe the data was valid. Best to check before painting
it matt silver.
