That's an interesting idea. I had been
doing things like Walmart garden gnomes,
owls, and such and dremmeling them to
accomodate the camera. I hadn't thought of
simply painting them since the black always
worked for me. I can't imagine you could
hurt it by spray painting it since it is
supposed to be watertight enough to
withstand rain. Like YKZ_pilot said, just
don't paint the lens/lenscap!
