I began using QEW this winter. I have followed the directions and the initial results are great. However, I've noticed that I now get large water spots on the horizontal surfaces of my car that I just don't remember getting before. I don't have access to a camera, but I would describe the spots as roughly dime to nickel sized, with about 25-50 spread out over the hood. They have not etched. Anyone else having this problem? Oh, I used Collinite in the fall and I NXT'd it about 1 month ago. I don't even know if it is related to the QEW and I'm not overly concerned about it, I am just curious.
