I am looking to build an ATS for my tank and want to build a light box rather than use a typical cone shaped reflector for it. Any ideas where I might find something local that will have a mirror like finish that is flexable. I tried Hobby Lobby and they didn't have anything. I found a flexable mirror at Wal Mart that will probably work but the information said to make sure that it stays flat, which I am guessing is more for image correctness rather than structural stability. Just thought I'd ask since I am sure someone has come across something that would work.

Thanks,

Bob
