Engine cases and internals, I can see the reasons for not doing bead-blasting. But what about the external thermostat on a 1980 911SC? With the thermostat completely disassembled, there are no crevices or internal oil passages. Is it safe to bead blast and then clean well?

Real world question -- I get the car back from the painters in a couple of weeks and the thermostat is cleaned up, reassembled, and in a plastic bag awaiting reinstallation!
