How To Tint Your Rear Windscreen
The rear windscreen is probably the trickiest window to tint on any car, but by using our guides below and one of our DIY pre cut window tint kits, you can achieve a professional looking finish doing it yourself, at a fraction of the cost of a professional tint shop.
The main problem with tinting the rear windscreen on a car is that it is usually curved, meaning that if you do not apply any of the techniques described below, you will end up with lines in your window film where it is unable to attach to the window correctly. There are generally two methods of overcoming this problem:
1. Cutting the film for the rear windscreen into several strips
This is achieved by cutting the film into several horizontal strips before installation, as shown below, and then applying them separately:

This will allow each strip to form to the shape of the rear windscreen and therefore attach evenly to it, eliminating any lines in the window film.
2. Heat Shrinking
In some cases where the rear windscreen is very curved, heat shrinking may be the preferred method. This is done by laying the pre cut film for the rear windscreen on the outside of the window, with the clear liner side up. Draw an 'H' shape on the rear windscreen with a damp cloth so that the film will hold to the window. Using a squeegee or hard card flatten the film to the windscreen as much as possible - you will be left with fingers of film running up and down. Using a heat gun, you need to shrink the fingers by moving the heat gun vertically up to the top of the film, or down to the bottom of the film - do not move the fingers horizontally. Take your time and be careful not to singe the film.
