I just cleaned my car yesterday with the rest of my Zaino Wash. I wanted to clean it up before this weekend so I could see the swirl marks real good and see what I would need for the PC. So I thought I did a decent job and took my time and dry it real good, but today when I woke up there where little specs of dirt all on the window when the sun hit it. Also the black paint still had water marks on it even though I dryed it with a leaf blower and waffle weave towel. Could it be that it is because the paint does not have any wax on it? I live near acouple trees and there is a industral plant down the highway. Could these be real bad problems for my paint and keeping it clean? How can I keep it clean for more then one day? Thanks
