Thanks for the response turtle. I fully believe Zandor's paper...but still being a hard head I just wonder where he gets the numbers. He writes that paint reflects 86% of available light, and mylar reflects 96%...is this a universal constant? I sound argumentative...I'm not smart enough about any of this to be a know it all..just askin. I suppose its not even that great of a diff when you get down to it, but painting for me is so much easier and covers so well, as well as being washable and smells pretty. Thanks guys.
