I need to replace my front nearside door but was wondering how I remove the black rubber outer trim incase I need it for the replacement door if it doesnt have the same trim?

Heat gun and fishing wire, Its just held on with adhesive foam.

Then Tar remover to get rid of the sticky left behind

Are you on about the door seals or the metal bits around the windows?

The foam/rubber trim that runs along the centre of the door. I may need to replace it onto another door and was wondering what would be the best thing to stick it back on with?

Halfords trim repair foam tape does the job, just make sure everything is well cleaned and degreased before using it.

Many thanks...
