You'll see lots more astronomical observatory domes painted white than silver - all to reduce temperature changes during the day and night. I had a solar filter with a homemade mask on my telescope - the mask was painted flat white and the filter cell was aluminum. On a summer day (like the 41C desert in Baja during the 1991 solar eclipse), the cell would get too hot to touch and the mask was not much hotter than air temperature. I can't help but think a thin layer of white epoxy paint would do more with less weight than a thin aluminum cloth if heat was the only problem. Strength-wise, the aluminum would help make a stronger skin in a number of ways.
