Well...here is what I have found with my bug deflector. The little tiny LIGHTWEIGHT bugs only splatter across the top 20 percent of the windshield now. The HEAVY DUTY bugs still make it through, but no longer clog up the windshield wipers. Overall, I did get a decrease in bugs which means I can ALMOST go three days before I have to clean my windshield. Short of racking the windscreen back 20 degrees, that will be as good as it gets. I also had to put billets in the grill - the bugs here in 'Bama are big enough to take out your radiator!
