Re: tailgate window
I assume you mean the track that the window sits in at the bottom of the glass as opposed to the trackes on either side. If so, I fixed this just last week. I completely removed the track, if it is not already, and cleaned out any loose rubber and dirt and anything else that is in there. I then filled it with epoxy and put the glass back in making sure it is aligned correctly. In my case, part of the track was completely rusted through so I actually rebuilt part of the track with the epoxy. I then caulked all the way around so that water running down the glass would not get caught in the track and rust it out again. I reinstalled the window and it works preferctly. Only been a week but I think it will last a while.
