You may have better luck searching "door seal".
I get the same thing (Seal punches up, squeaky windows). I usually just need to wipe down the seal as it gets dirty.
This type of product may also help:

The streaks you see on the door are actually from some felt guides in the door. Your Window is probably slightly etched in those places (I have the same issue). Keep your windows clean or make sure they are clean(er) when you roll your window down. The felt pads will trap some dirt and be abrasive against the glass.
A friend and I just talked about the windows in the BRZ/FRS (He is a Toyota mechanic) and he said there are some special tools to align the window and make sure the senors are all correctly positioned. He said their dealership doesn't even have those tools.
As for searching these forums, I found google much better. just type site:
www.ft86club.com in the search field and it will return only results from this website.
