Black cars look incredible when clean, but are very tough to keep that way. Ditto on the waxing. I have had great luck with the Zaino, including using both #5's (swirl marks and small scratches) and #2 for the shows as a finish gloss. Even body detailers tell me how great it looks - after 11,000 miles. I am just glad that Woodhouse is going to "refresh" my Zaino job while it is sitting there for the next several weeks and I am not dinging them for a rental car - right Bill? ;o)
As for owning a black car, I absolutely would buy another, another, and another. All three of my current cars are black (Viper GTS, Durango GTS, and Yukon XL) and many of my previous cars were as well (Suburban, two Impala SS', two Buick Grand Nationals, Lexus, Navigator, etc.). Tough to keep clean? You bet. Worth the extra effort? Absolutely!
