I thought I would be smart, so poured a bottle of Rain-X into the windshield washer fluid reservoir, mixing it with the washer fluid. Plugged everything up. Had to replace the little rubber hoses running to the windshield wiper blades and the little nozzles on the wiper blades.
If you drive really, really slow (5-10 mph) most bugs will not smash into the windshield. Kind of hard to make any $$, but you won't have to deal with the bugs.
I use rain x. Then when I sleep at night before I crash I spray the window with that 98 cent bottle of Walmart glass cleaner. In the morning they come off with the wiper blades
my reply to the actual question submitted is a bug shield which mounts on the hood just above the grill/at the end of the hood. it creates some form of wind flow that really does prevent the bugs from hitting the windshield. imagine a wind tunnel. a great investment for $100 bucks PLUS the labor to install. those stainless hood wings work but cost too much. the tinted/simple hard plastic design is all one needs.installation is under an hour for the most part. in short,YES,bug shields work.
One thing's for sure about the bugs hitting your windshield: they won't have the guts to do it again!
