Go for collinite 476s - its the most durable wax on the market I have found it to give a better barrier to bird bombs before paint is etched.
You will only need to wax twice a year with the 476s (I do it every 8 weeks as i'm insane OCD)
I have found also that bird poo around this time of year is worse and more frequent as the birdys are flying to and fro the nest like madmen.
Also they seems to eat lots of berrys which make their poop even more acidic.
