Bob,

At work, a sub-contractor used white pigment in the epoxy/glass lay up for a
very large radome mounting ring (3m dia.) for a microwave test site.  The
rig has been completely outdoors for almost 4 years now and shows no sign of
UV degradation.  It also has a blue foam base.  The laminate was much
thicker that our Europas but the environmental exposure was more severe too.
