> White paint might be almost as good > (aluminum paint has a lot of variability in how "shiny" it is.) Aluminium/silver paint I tried does coat well but it's rubbish for this. The particle size is too big and didn't produce the mirror I hoped for. I have some 3mm plastic mirror somewhere, would rather use that instead of aluminium paint. White / light colours (or Hot Pink !!!) are best http://home.clear.net.nz/pages/joecolquitt/led+lcd.html OK, I'm done for now. Maybe next week if I'm in the fabricators I'll get some coloured acrylic scraps and try it out -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
