Window tint no matter where it is purchased is a multi-layered film.
Usually the glue layer,
The coloured layer is the bit that blocks out light and gives ultraviolet protection.
This is not simply coloured plastic, this can be various types of products: -Dyed film, Crystalline, Metalised Film, Hybrid Film, Carbon Film and Ceramic Film. These vary in prices and in most cases the cheaper films are the most difficult to remove and don't stand the test of time compared to more expensive films.
Then followed by the anti-scratch layer which is the outer layer.
One of the comments stated that the film on their car was just coloured plastic and because it was installed in a car yard it was rubbish. It may have been a cheap product and a dyed layered film. But at the end of the day, the car yard would be in quite a lot of trouble if they sold a product that wasn't doing what it stated. i.e being window tint it would have to be an Australian standard product. If the car was involved in an accident etc then there could be lawsuits if the product they installed was a contributor to it.
I had car yard film on my Evo X. It has been removed to install the Suntek film. I didn't remove it due to it simply being coloured plastic, I removed it due to wanting the Suntek film on the rear doors and wanting the car to match. It was most likely a cheap product and yes it took the window tint ages to take off. But to aid in removing the film when it comes off in small shards it can be heated with a household steamer and heat gun. Also, the car yard film had less scratch resistance than I liked. The film did exactly what it was supposed to do and didn't fail at all apart from scratch easily from some dirt on the window rubbers which at the end of the day is more of a car design fault to allow dirt and dust to sit in the window channel and rubbers.
Privacy Glass
Privacy glass that's found on most new cars is exactly that privacy glass. It is simply dark glass and doesn't offer much in the way of heat and ultraviolet rejection. Privacy glass can be tinted with a clear or light window tint to give 99.9% UV and heat rejection.
I currently have Suntek Carbon Window tint 35% on front doors, and 70% on the rear doors on two of my cars and it provides very good heat and UV protection. I would highly recommend installing clear or light percentage films on the rear privacy glass to help with heat and UV.
