About a week or so ago there was a post about squeaks in the roof. I though it was coincedental since I had my roof off for several days and noticed squeaks when I put it back on. Responses to that post suggested that dirt on the weatherstripping was the cause with suggestions to clean it off and apply a silicone grease. I planned to do that when I got a round to it. Well, today, the squeak was worse and I noticed while driving it got louder when I applied light pressure to the rear of the panel. Here it comes: My roof is separating!. I had the glue injection fix done last March.
I also noticed a drop of liquid near the front edge of the panel. It smelled chemical and had a slightly greasy quality to it. Don't know if there is a relationship. Didn't see any separation along the front.

Thanks for the detailed response. However, there is another cause for squeaks/pops. In my case it's delamination.
