The best way to install security film on a side door window is to remove the glass from the unit. Unfortunately, it will take a little more time and expense to finish the installation job, but the extra effort certainly has its benefits. It will provide greater protection to the window because you'll be able to apply the film from edge to edge creating a better bond. It also allows you the opportunity to charge a little more for the installation.
If you are not mechanically inclined, we recommend using a glass shop to remove the glass for you. In general, it will take anywhere from two to three days to complete the
job if you decide to remove the side roll-up window from the car. Always check with the customer first to make sure it's O.K. to leave the car for an extended period.
Note: frameless side windows do not offer the same security and protection compared to framed windows.
