Well thanks to Mandy and the staff at Maranello I now have the answer to my questions.
All the black bits, ie sills, windscreen frame, body line over the roof at the back of the cabin and mid way recess are all Satin Black. (The sills are stone chip satin paint). Also for clarification, the black mid way recess line should be painted not tape.
Big thank you to Mandy for her help in sorting.
