I've used them all, and I feel that Wizards is the best. Its Mist-N-Shine product definitely gave me some noticeable improvement over Meguiars and Mothers. I don't have black, but have a friend that does, and he won't use anything else. His paint is absolutely beautiful. I buy mine at Carquest Paint Center. You an also buy it direct from Wizard......www.wizardsproducts.com
