Not the rubber seal around the glass sunroof, but the thin long (U shaped) seal that attaches to the housing and seals against the sunroof rubber seal.

This seal is apparently glued to a metal rim. Mine has come out twice...blowing back over the car after I opened it.

What is a good rubber cleaner and apoxy to attach it back to the metal?

 

urethane

 

Looking at it today, it appears to be a drip tray. It attaches with two plastic pressure clips below the rear corners of the sunroof.

Is there any easy way to get it out? With the sunroof open to vent, I can't maneuver it out.

 

Mine is coming unglued on the ends as well. I may try a dab of RTV sealant on the ends
