An interesting problem was reported arising from windows on a 2007 Volkswagen Eos (a convertible) that were tinted with film that was reflective on the inside surface. It seems that the owner left the top down and the windows up, and sunlight reflecting from the concave inside surface of the glass then burned a big hole in the plastic trim on the door.
There are more details (and pictures) documenting this problem at this post in the VW Vortex Eos forum: Tint on Eos. It might be something for you guys (tinting professionals) to think about - maybe you need to make sure you use a film that is not reflective on the inside surface, or perhaps maybe you need to tell the owners to not leave the windows up and the roof down at the same time.
