The bottom lefthand corner of my rear glass weatherstripping has begun popping up and out of the trough for a while. I want to glue it down somehow, but don't want it to look like hell. Has anyone done this before? What do you recommend? Is this an easy DIY or body shop task? New seal? TIA.

 

New seal in the UK is about £40 so about $60. Takes no more than 30 minutes to replace including cleaning the gunk out of the screen recess.

 

That is probably the proper solution. I used a small ball of 3M weatherstripping glue and it seems to be holding up.
