I live in northwest PA and in the winter have to deal with salt on the road and grit put down by PennDOT. My outback, even though it has no outright cracks, has small "pits" all over my windshield caused by other vehicles throwing the grit. Does anyone know of a way to help "clear up"my windshield as some of these pits are right at eye level and are quite annoying. They are too small for a windshield repair kit. THANKS!
