I was about to do a bit of patching up of the ceiling above a 60W
mains light.
It is one of those flush fitting jobs (and should probably be flushed
down the
toilet, but that's for another discussion...), so it gets pretty hot
inside.

Anyway, I found another way, but the question remains: can we use
ordinary
caulk in hot environments? Not cookers, not fireproofing, not heaters,
just
around ordinary mains lighting?

Thanks,
David P.
