what is a good wax to use on a black camaro

It would depend on what shape the paint is in, and how long you want the product you use to last. If you want something to last months and not weeks use a full synthetic product like Zaino, Liquid Glass or Klasse, if you want to use a wax product try P21S, Meguiar's Gold Class or Mother's Reflections, if your paint is in good shape you do not need a cleaner was product, if your paint is in bad shape you may want to use a product like 3M Scratch and Swirl Remover to get the paint looking good before applying polish/wax.
