JWF, Rear Windows - Wet Shrink Pattern

"Wet Shrink" Patterns

Now that you have given the rear window a good inspection and cleaning, it's time to cut a film pattern on the outside of the rear window. Make sure your measurements are exact so the film can be easily installed. If you are using the "wet shrink" method, please proceed using the following steps:

Tools Needed: Spray bottle with cleaning solution, Olfa knife, Squeegee and Button

Spray outside of window with solution.
Step 1 – spray outside of
rear window
Cover entire window with film, factory edges at top and bottom.
Step 2 – place film
on window
Trim Trim the pattern 1/4 to 1/2 inch oversize to allow for edge damage during shrinking.
Step 4 – rough cut
on the sides

Spray outside of rear window with solution to make it easy to move film around.
Place film on the outside of the rear window (make sure factory edge is on the top & bottom and the liner is facing you) and cut a rough pattern with atleast a 2" overlap all around to give yourself extra film in case of an error.
Next, place a button underneath the film and use it as a guide to cut the film without cutting the glass. Take your Olfa knife and poke it through the film against the button.
Most new cars have a 2" to 3" deep black border around the entire rear window frame. Your first "rough cut" will be to cut a pattern that overlaps the border by a 1/4" on each side, and by 1" on the top and bottom. This will provide you with extra film in case an error occurs during the shrinking process.
Remove the button from underneath film pattern.
