I've managed to open my door onto the side wall of my house and taken a small chunk of pain off the door edge. I've seen this stuff: http://www.chipex.co.uk/ra/?utm_expid=35337439-16.oweEKOZiQ3iqEPGTSC-Igg.1 and wondered if anyone has used it/had any experience? It seems good from the videos & feedbacks etc, but always good to get a forum's opinion on things like this.
