Hi, I am trying to install new window runs in the front windows. I have Fatmatted the doors and do not want to cut through that to install the new runs if at all possible. I started at the front and installed the new run by spraying silicone spray on the metal track of the door and then sliding the run into it. It worked great for the front. Then I put the run into the door frame over the top and down the back. I am stuck at the rear of the front window. I siliconed it a few times but just can't seem to get enough of it to slide into the door frame. Does anyone have a good way to do this, again, without taking the trim panel off, etc? Any input will be much appreciated. Thanks, Dan.
