You could sandblast the aluminum surfaces you need to be flat black then anodize them with a good black dye specifically made for anodizing. Any water based food coloring or fabric dye will work for anodizing but blacks tend to look a bit greenish, thus the specially formulated anodizing black. If someone would develop a DIY Vantablack coating process... Vantablack is neat stuff, the blackest substance ever made. Something to do with carbon nanotubes and would make a perfect antireflection coating for the inside of telescope tubes and camera parts. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
