Yesterday, removed the Arizona badges from the side of my 2.5. Definitely looks cleaner.
Used some dental floss, a store card and some WD40 to help clean up post. All good stuff.
Then I had a brainwave and decided to do the rear.
Started with the MX5 badge. Same process, came off fine. Unfortunately, the MX5 badge is NOT only held on with adhesive. Removing the badge has left 2 small halls (balls is the appropriate phrase).
I think that my solution will be a GB badge over the top of the holes, but thought that it would be worth mentioning on here for anyone else who might be thinking of it.
