Heat Shrinking Tips

As we've mentioned in this Rear Window Installation section, there are two types of heat shaping techniques—wet shrink and dry shrink. If you prefer to use the dry shrink method, here are a couple of valuable tips to help the film cling to the glass if you are
not comfortable working with baby powder.


Fabric Sheet Method
Get a hold of some ordinary laundry fabric sheets (e.g. Downey). You will use the mounting ingredient within the sheets to help the film cling to the glass. There are
two ways to perform this method:

1. Wet fabric sheet and rub over entire outside rear window. The mounting ingredient from the sheet will leave a hazy appearance on the glass. Let stand for a few minutes until ingredient is completely dry. Apply film to glass and proceed with dry shrink heat shaping steps.

2. Shake or rub dry fabric sheet over entire outside rear window making sure the mounting ingredient particles from the sheet transfer onto the glass. Apply film to
glass and proceed with dry shrink heat shaping steps.

Whichever fabric method you choose, make sure to allow yourself enough time to clean the exterior of the rear window thoroughly.

Carnauba Wax
You can purchase Carnauba wax at any automotive retail store. Apply a light coat of
wax to the outside surface of your rear window. Let stand for a few minutes until wax
is completely dry. Apply film to glass and proceed with dry shrink heat shaping steps.

Again, the wax will help the film to cling to the glass as you dry shrink. FYI, the wax
is easier to clean off the glass compared to fabric sheet particles.

Ivory Soap
A new technique is taking a wet, soft cloth and lathering a bar of Ivory soap on it. Once the towel is sufficiently "soapy", rub it on clean rear window and allow some time to dry. Apply film to glass and proceed with dry shrink heat shaping steps.
