I have a 4quot; tear in the plastic drivers side window. Are there any adhesives or techniques to fix it?
None that will look nice. You could use a thick clear tape however it will look ghetto.
Clear packing tape. Both sides. A couple of layers is good. Mine was cut about 3 years ago and when it starts to peel I just rip it off and do it again.
I repaired mine with clear packing tape, then took a hair dryer to it, just Long enough to warm it pretty good and got as many air bubbles out as possible- it lasted a full year and didn't block my view (for shapes and light, not 100%) then finally replaced it. By the way, my tear was all the way from top to bottom!
Unfortunately, any repair will be only temporary, and you will never be able to do an unnoticeable repair. Some very good clear packaging tape on either side applied on a warm sunny day, perhaps even followed by some mild heat from a hair drier.
boat or auto supply stores sell a clear repair tape for plastic windows that doesn't yellow or peel like tape does
