I picked up 3M brand adhesive and wax remover from Auto Zone, I'm sure one of your local auto parts shops carry it. I needed something heavy duty, because one side must of seen more direct sunlight and had turned the adhesive hard. Like Phi said use wax afterwards to protect the paint. Especially if using the 3M brand. Bowlofturtle waxing by hand is safe, maybe you're thinking of buffing?
