Martin:
Why do you think they call it "miracle" glue? It 's a miracle if you can get it off?
Sorry , couldn't resist.
Removing the glue without removing the paint will be tricky. Goo Off, 3M Adhesive remover, even Bug and Tar-Off may work without damaging the paint, but as Pete says, be careful with this highly volatile stuff. Don't use a heat-gun after trying the chemicals, or you'll remove more than just the glue

John Rickard told me he worked on his 944-Spec for about 8.5 hours to get about 5-Lbs of glue and carpet weight out, so elbow-grease will definitely be needed.
Good luck!
