This WIS doc make help:

There is no plastic on the top - just the canvas. There is a seal on the underside of the glass frame. Its nothing more than the same self-adhesive "Frost King" foam weatherstripping you can buy at Home Depot. It sits against the canvas is and compressed when the bolts from the glass are tightened onto the frame.
The headliner does have a plastic strip on its edge that snaps into a channel in that aluminum frame. Maybe the noise is there?


Overall look on aluminium frame under rear window
Plastic stripe
Groove on the frame
If you don't mind I'll add some photos. I recently replaced roof on my CLK so i have tons of photos related to the topic


Later I found very helpful video how to replace water pockets it can help as well
(unfortunately video quality is poor)


I also installed Robbins soft top and my opinion exactly the same as Rodney's: quality is really nice.
As for the Robbin's top, the only part of it that seemed less substantial than the OE was the water pocket and the plastic tabs that fit at the base of the C-pillar area. Those pieces just seemed much thinner than the original stuff. Otherwise, the canvas and seam was at least 10% better than OE.
