I have a few questions, I saw where you used Pinnacle Souvran as your LSP on this red ES but you have used other waxes/sealants on some of the black cars you do. Most say Souvran is the best on black cars and brings a shine and look that is pretty much unrivaled but it is expensive and does not last very long. Is the Souvran you used the $80 carnuba paste wax specially formed for black/darker cars, does the customer pay extra to have it used or request it, and what was the reason for other last step products being used on other black cars then Souvran? How does the look of Souvran compare to collinite 476 and Natty's blue?
