YES IT DOES!
When glass is tinted, a slip solution is used to help in cleaning the glass properly, applicating and positioning of the tint. When excess water is then removed with a squeegee, there is a fine vapour of moisture left behind under the tint.
Not visible at first the water vapour may begin to "pool" due to natural surface tension. This is a natural process that occurs in water molecules.
This will be noticeable from both outside and inside. This moisture will evaporate over 2-5 days depending on heat exposure. More sun = faster drying. Cold or rainy weather will slow down this process!
The thicker the tint -the slower the drying time and tint may appear cloudy.
One thing you can be sure of : Window Tint ALWAYS dries out.
