Just a quick note/question regarding the UV comment and clouds. Is it
actually true that cloud cover reduces UV exposure? I've heard that you
need as much sun screen when its overcast as any other day.

UV gets through, but it is reduced. You certainly don't "need as much sun
screen when it's overcast as any other day".

Does anyone know the real answer?

Pretty much anyone who has spent long hours outside in the middle of the
day, under clouds and not under clouds.
