today (6/7/2016) i received an email from one of our custumers and this is what it said with this image attached;
"I recently had my back glass broken and it will be getting replaced tomorrow. I would like to get an appointment to get it replaced as I had the original tint installed by your shop a few years ago. I would also like to say that the safety aspect taught by your site is very true and I can personally attest to it. Because of the tint on my back window I was able to drive home about 40 miles from a friends house where the window was broken."
this is a good example of how tint can help in other ways, not just heat rejection or privacy. tint can hold broken glass together, it not the purpose of the film, but more a happy accident.
