I use Meguiars Carnuba exclusively. I have friends who have Black cars that use other products, including Zaino, and I can't tell the difference in shine. I normally wax once a month anyway (any time in the garage is good time...:cool ) so longevity is not an issue. I'm sure that other products may be better, but I'm happy with the result and I always receive compliments on the finish.
