The mouldings and badges are stuck on with a double sided type tape. They are easier to remove if you have a heat gun or a good hot hair dryer. Be careful not to leave the gun in the same spot for too long or the paint can get too hot and bubble. And the adhesive will come off easier if you use a good adhesive remover like 3M General Purpose Adhesive Cleaner. This cleaner is strong, but is safe for automotive clearcoat finishes. If you have light scratches from removing the badges/mouldings and cleaning off the adhesive, you can easily buff them out with any decent brand clearcoat scratch remover like Meguire's Scratch X.
