I have a black 05. Sun + hard water = water marks. Best thing to do after washing it is dry it in the shade or better yet in a garage. Sun usually causes water marks and spots in a min(minerals in the water help too). So unless u can dry your car in under a min, get it out of the sun. Forget coke and vinegar...you're youre just gunna do damage to the paint and remove wax, especially since the marks will juust come back when u give it another shower.
