has these waterspots in it. I'm pretty sure it happened when I washed the car a bit too soon one day last month. Now I can't get rid of em. Even after a fresh car wash, these things are still there. Is there anything I can buy to remove them?

 

yup, you can buy white vinegar!

try it - it should work... if not, then detailers spray or if that doesnt get it, then try glass polish.
zaino makes one and there are several others out there-
let us know how the vinegar does

 

clay should work too
