We had a million love bugs on Vegas from track to home (51 miles) Saturday. There were so many the front of unit smelled like aquarium with no water in it.
They were also on racecar windshield during runs Saturday before car lost wheel and ran tree over.
I learned a long time ago to use Rain X on glass and the green stuff in windshield washer. I also never use wipers unless absolutely needed. Only smears and makes things worse.
Do not let them bake too long, best to get off ASAP. I cleaned them that afternoon. Never forget coolers up front, radiator, trans cooler, etc. They will plug them up. I have had luck with just washing them out with sweeper nozzle.
