Not on the window... haven't ever used the stuff myself either, don't even think it could be applied on a window, but all around the back glass should help a little. Someone else who has used it, and maybe even had to fix this same problem will prob be able to give better advice.
Take it to an audio shop or a body shop. They're usually pretty good at fixing that stuff. And if you think that's bad, try stopping the rattle of a back hatch on a 1985 Jeep Cherokee :P.
yeah I was going to say try an auto glass shop. they can secure the window with more of that black stuff they use as a sealer.. that should help quite a bit. They may also have ideas for more reinforcement
ROFL! I worked at an autobody shop (still do, just too slow for them to have any work for me). Ask them if they have anything different. We have some 5115 here (it's white) that'll hold that bish in so tight, you probably couldn't kick it out... But you have to have a glass clamp to use it, and it's not cheap stuff. I just did it to my Cherokee, didn't want that thing coming out or start leaking like the windshield did...
my 93 camry rattles where the room meets the rear windshield almost in the center of the windshield i put my palm ontop and it stops rattling .... how is that possible ... outa all things i mean comon how random so many problems with this car didnt have reverse for over 2 months finally my parents paid for a transmission .. ouch brakes cut off in the middle of i95 .. that was wow everyone i know with my gerneration camry is ragedy i dont even got inside door handles they broke off before i got them u gotta open the passenger door from the outside
ROFL! I have a 1987 Honda Accord for a work car (fuel pump is out of it, and I'm not looking forward to replacing it), and it's never had a driver's side door handel (outside). I usually leave my window down unless it's night, or winter.
