Rob:
I'm not an engineer, but my common sense tells me that a metallic paint
will reflect more solar energy, leaving less to be absorbed by the
structure - thereby making your contemplated choice better than
non-metallic. In fact, aren't the UV barrier paints just metallics?
Keep up the good comments.
Yours,
Al Fuller.
