Front and Back Window Preparation
You will need to remove any parts of your vehicle which are in contact with the glass surface area to aid in the installation procedure.  You may need to remove inner plastic pillars, tape back the felt window draft guard or even remove the door panel trim to have good clear access to your window. If you want professional results, you will need to take the time to prepare your vehicle.

Rear Windshield Window Preparation
You may need to remove the rear deck trim or third brake light housing to have good clear access to the rear window and allow for proper heat shrinking and excess water removal.  The rear window is the most difficult window to tint. Take the time to prepare this area as this is where most mistakes will occur.
