Window Tint Installation - How to "Heat Shrink" Your Front and Back
Windows
Front and Rear Installation of Precut Window Tint:
To lay in the precut tint, roll it up and reverse the liner and roll it out onto
the prepared inner surface. Squeegee it out, etc. Fingers or creases at the top
and bottom will appear. Use the below technique to remove fingers.
You must use a heat gun on high
setting, a hair dryer will not work. You are only shrinking the finger itself,
just pass the heat gun over the finger quickly until you see it distort
slightly, then smooth it out. If you spend just a moment too long over the
finger it will burn, or shrink unevenly. The trick is not to crease the film
when you smooth it, so the first time use a rolled up paper towel to smooth the
finger down to keep the film wet against the glass, otherwise larger fingers
will bind and crease if you use the application card first, repeat the process
with a grey application card.
Note: the film will only shrink properly if the fingers
are aligned with the grain of the film. As you unroll film from side to side the
proper grain direction is up and down, i.e. If you have a window 45" wide
horizontally and 18" vertically, using a 20" roll, the fingers need to point up
and down toward the straight factory cut edge. Fingers always need to be moved
toward the factory edge. Squeegee a horizontal anchor onto the glass to anchor
the middle and sides moving all the excess to vertical fingers.
