A coating like GTechniq C4 or Carpro DLUX will certainly help far longer than any wax or sealant. I'm not sure if many waxes or sealants provide a UV barrier,
saw somebody on here that laquered them...
can't seem to find it now......
do you have headlight washers?
if so you will need to use some decent hard wearing stuff as the window washer solution will probably be very strong!
C4/Dlux will definitely hold up to this - so will FK1000p, although good shout and something I'd never really thought about.
