Rear Back Windshield Preparation for Precut Window Tint:
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.  With a side to side window use a scrubby pad to clean the defogger lines and rear back windshield, then with a squeegee remove the excess water with a side to side and then top to bottom motion.

The rear window is the most difficult window to tint. Some of our precut window tint kits are designed in two pieces to aid in application. Take the time to prepare this area as this is where most mistakes will occur.
