I should qualify that *some* rubber gasketed boxes are OK. Some bottom 
out on metal to metal contact and have the gasket outside that metal to 
metal contact.

Most electrical-type weatherproof boxes just have the cover sitting on 
the gasket. These aren't shielded fully because the gasket insulates the 
cover and the only contact between the cover and the case are the cover 
screws.
