Well, the rear window seal project is done. It was really pretty simple. The toughest part was getting the new seal on the glass. That was pretty scary, the new seal is a tight fit and I was very concerned about busting the window. A little tip, put the seal on from the bottom of the glass, that is from the inside curve of the glass. I hope that makes sense.

The trim was the next hardest part. My hands were pretty sore by the time I got it all in place. Roping the assembly into the car was by far the easy part. It took more time to align the assembly in the opening. Take your time in doing this part. I used parachute cord, place in plastic bag and added some talcum powder. Put the cord in the seal and you will need a helper to place the assembly in the opening. Take care to get the lower lip of the seal placed correctly and have the helper apply pressure. Pull the cord very slowly. Start at the bottom and pull one side about 6 inches and then go to the other side. Make sure you have glued the headliner into place. I used rubber cement. After you have rounded the bottom corners make sure you hold on to the upper portion of the cord as you pull the lower or it will pull back thru seal channel. As you approach the headliner, take it easy. Again, glue the headliner very very good! If the cord pulls the headliner from the lip, stop and remove the assembly and re-glue. You will never stuff the headliner back under the seal once you have pulled it in. I was left with about 3 inches of seal that had to be pulled in with my fingers. Not fun!

I used 3M glazing and bedding compound to seal the job. The body to the seal joint requires lots of sealant. You will not be able to just put a thin bead in this area, especially at the corners. Masking off the body makes cleanup a bit easier. This sealant is pretty nasty stuff.

The glass to the seal joint is ugly. The plastic tip of the caulk tube will not push into this area. I had to use a small putty knife to open the joint and follow along with the tip to put a thin bead into this space. Here a thin bead is all that is needed. Again, masking off on the glass is useful.

In the beginning I was very tempted to get a pro to do this job. I did not want to spend the money and I am pretty stubborn about doing all the work on my car myself. In the end, I am glad I decided to do it myself. This job is actually pretty easy.

I need to do that job also. What was the secret to remove the liner panels from the roof pillars?

See the attached picture. The liner panels are pretty simple. Push the cloth trim away from the front edge and the panel has recessed notches that push out of slots in the front edge of the pillar. The hard part is the clip in the upper back corner. I had access to a tool that is basically a medium length screw driver with a hook on the end and a tapered point. Sorry I do not have a picture of the tool, I had to return it. I pushed down on the top of the clip on the body and levered the panel out. I have yet to re-install the panels, I want to re-glue some of the material to the panel.
