Another trick I used a few times when I took stuff off my Evora and Elise was a painters Halogen light. Don't cook things, but a nice warm surface makes things much more pliable. As pic shoed you, pull up and stretch to detach, I'd avoid the scraper if at all possible. I'd rather just repaint a nose than deal with this damn stuff ever again. It is a flawed product esp as it ages. Even 50-75 yr old Ferraris have this really cool thing called PATINA.
