Anything by Meguiars or Mothers is good for a dark colored car.
First of all, what kind of car do you drive? Different types of paints have different results
Here are the routes you can go that I would recommend:
-Meguiars #9 followed by #26 works EXCELLENT (Bright shine and unbelievable depth)
-Meguiars polish followed by Meguiars Gold Class wax (Different type of shine then the first system)
-Mothers 3 step system (Great shine, buffs off easier then Meguiars, but doesn't last as long)
-3M Imperial hand glaze followed by paste wax (I used Classic, but you can use Eagle one, etc.)
-Zaino (Easy and great shine, but some cars react poorly to it and it might smear and shine might be dissappointing)
Those are my top picks as far as wax goes.
