Zorro, it depends on how you want to take care of it and what kind of shine you want.
If you want the very best shine,have a garage to keep it in and are willing to wax at least once a month then Pinnicle Soveran is one of the top rated waxes. A carnuba wax of that type will give the deep reflective shine that many people like.
If you don't want to wax that often than one of the synthetic polymers would be better. Klasse SG and Zaino are the top two that I know of. They give a harder more brilliant shine but perhaps not the depth of the carnubas.
