After about 6 hours of removing tar spots, polishing and waxing, I finally had a shiny M5 yesterday. The effort nearly killed me

This morning, I looked out of my bathroom window to check on the cars, and I found these little buggers all over it again...
Now these things come from a local stream, and I think they assume a shiny surface is a river, and land.
Unfortunately, they all die for some odd reason, flip upside down, and glue the wings to the paintwork.
Question is, is there some product I can use to protect the paint that will make it easier to remove the glued on wings?
I've used AG Super resin polish, and I'm going to get some of their harder wax polish as well...
But... what better place to ask the advice of experts

Any thoughts gents?
