I can relate.Man I made a mess last night.
I separated the passenger window from its track because it was already coming loose. I cleaned the window with glass cleaner and I tried cleaning out the track with a rag and brake clean. Then I tried applying fresh adhesive. The window glass had a black "pad-like" material on it where the track used to be. I wasn't sure if that was old adhesive or a separate part so I tried adding new adhesive on top of the old material. Looking back on it, I am thinking that was probably wrong.
Anyhow the adhesive I was using was this stuff from 3M. I bought it many years ago and it has just been sitting on the shelf. The viscosity was so thick that I could not get it to squeeze out of the tube. I started trying to step on it to get the stuff out. Only a small bit (1/8") would come out at a time. Then it started leaking and getting everywhere. After a while I got frustrated and sorta stomped on it. The whole tube blew into two pieces.
I said screw it and just used my hand to scoop out the adhesive and apply it as best I could to the window and the track. I got that stuff everywhere. It was all over my hands, I got it on my tools, my clothes, etc.
I didn't take any pictures, but I should have. Both of my hands were black. It took forever to get it all off.
Fingers are crossed that the passenger window is firmly glued to its track now. I got a little bit of glue on the window itself, but not much. Hoping I can get it all cleaned up.
I have done that once or twice.
It's frustrating but now if it's dried up cleaning the window is easy with a razor blade
