Glass "polarizes" light to a degree. Different types of glass have different characteristics. It happens when light is reflected and refracted. Light rays from a given source are scattered. They travel in all directions, and are reflected and refracted by most all surfaces. Polarization merely gets all of the rays coherent, travelling in the same direction. As light travels thru glass it is refracted and reflected between surface A and surface B, then it is further polarized by being reflected off another glass, or other reflective surface. Depending on the thickness of the glass, and the amount of times it "bounces" between surface A & B, the effect can be quite dramatic. Lami glass, for example has 6 surfaces to further bend (refract) the light.
This is an over simplification, but it gets the point across. While not true polarization (All rays travelling along the same plane, in the same direction and angle) It can be quite dramatic. A polarizing filter (some films, sunglasses, etc.) will dramatically alter the characteristics of already semi-polarized light.

WHEW!!! So.........In short, FilmBlazer is right tell the custy "I would tell the customer to enjoy the pretty colors because you can't do to fix it "

Oversimplification?

Come on key, let's hear the whole thing! Good post man.

Thanx V. Thats a compliment coming from you. I forgot to say that a plain old glass prism is a prime example of the effect of refraction to the extent it breaks light down into its component frequencies. Thus, the "pretty colors!"

My 2010 Nissan Frontier has been tinted 3 weeks ago but now the driver window film looks like a rainbow. Can someone tell me why is this happening?

[kats2112]

Are you looking at it under fluorescent lights?

With sun glasses ... ?

Maybe is is picking up a reflection from the bumper sticker

[Dennis_M]

many films will look like this thru polarized glasses
