ok I've always have White cars or My Pewter Z28 which basically don't show a damn thing in the paint and really shine with a basic clay bar, polish, wax routine but... I now have a 2017 Colorado and its Black. Looks wicked when clean but I washed it today for the first time and damn.. there is some haze already. What would it take to get the paint really nice? Any Tips on how to keep it at its best?
