>>9322622Really depends on what you're talking about but I usually paint the inside/underneath silver and then put a heavy coat of transparent blue over it. It obscures it enough that you can't make out anything but the silver still gives it a nice shimmering effect. You can kinda see what I mean with this T-10 I did. Although its not a good example since obviously it doesn't have more modern camera optics which have a bigger empty space inside.
