Nothing new to suggest other than some reliable bug remover liquid.
Frankly, Chuck, I've just about given up on keeping a wax on the front end. Between all the tiny pin-head sized chips that I touch up every wash & the endless bugs that I remove almost nightly after the drive home I figure as long as I can keep it sorta clean I'm coming out ahead.
Same kinda hatches occur every early June around the Mississippi. On our honeymoon so many years ago, the wife & I drove through our first 'Mayfly storm'. We ended up spending the night in some 2 bit hotel simply because you couldn't keep your windshield clean enough to drive any longer. Wipers just smeared the little buggers; washer fluid was the only way but I ran out quickly. Literally clouds of them! It was one of the most unexpected things I've ever come across while driving.
We don't drive the Mississippi (the Great River Road) in June any longer!
