I prefer to vigorously go over the entire ship (including the canopy)
with nice fine steel wool - gets rid of all the bugs and mud collected
at "low altitude", stops annoying glare (a definite safety plus!), and
when a refinish is finally due, most of the hard work is already done.

Wax just gets in those pesky holes - "static ports" I've heard them
called by local pundits - but I usually fill them with epoxy anyway.
Anything that small can't be of much use, after all.
