Why do my windows look foggy immediately after tinting?

The window tint applied to the glass has been sprayed with a special liquid.  This allows the tint to be moved around and positioned properly. Once in place, the film is squeegeed to remove as much of the liquid as possible.  This is what is seen in the glass when you pick up your vehicle. Over time (usually 1-2 weeks), this will evaporate as the tint cures.
