The seal is not actually glued onto the door.It is attached by small white push in clips

thanks for replying , I had a look and there is an open joint, one end was hanging down about 9" long and being able to see the back it is flat as if it had been glued. I have just been out and checked and there is no sign of any push in clips, the door is sticky where the rubber sit's as if it is glued on more like a double sided sticky tape . I need to confirm this is the actual door and not the door frame cheers

thanks for that

, any particular type of Gorilla Glue do I need to get ?

Gorilla glue is the brand, it is a super glue type, seem to remember the seal was originally just glued in place at that point, don't remember clips, but could be wrong

any type of clip or retainer would need to be close to the joint of the 2 ends and there is no sign of a retaining clip or peg. thanks
