I was parked at school, and it was a windy day. There were sprinklers near where i parked, but not right next to it. When i got back to my car later that day, i saw that the water from the sprinklers had blown onto my car, and then the water dried. Now there are severe water spots on my hood. I tried waxing it down, but then you can still see it. How can i get it out?
