Porsche 924 Door Seal.

[Earl Is The Name]

Hello All.
Is it possible to repair a deformed door seal ?
Looks like one of the repair monkies has shut the door with a cable passing through the door.
The door seal is now letting in water. (There is a song in there somewhere.)
It looks as if it is very difficult to remove as it appears to be glued in.
There is plenty of replacement options from an original seal to a generic part.
I would like to try a repair first.
A hot air gun is on the cards but has anyone tried this with success ?
Cheers.
