Yeah I would take take the wax back too. If it were any other color I would say def give it a shot. Gold Class will do a great job on Black as I said before, but the color isn't a good testing ground for experimenting with different brands when Zaino is in the mix. If a product is fussy the color won't hide it like silver or white. Stick with the Zaino and maybe buy some clay bar or some of the meguiar's Gold Class brushes like the ones for the wheel face, tire and carpet. Excellent stuff, I have all but the body paint ones (brushes on paint!
)
