alot of scraping and time gets them off, i used a 'blunt' screwdriver, carefully.
i used a tube of evostick rubber glue, did the job pretty well. Some glues can melt rubber so read label. I also had four small plastic clamp type things (got them from machine mart i think) which were very handy to keep areas in place whilst glue went off, then moved on to the next area. One door at a time.
