I have Blackhole and Amigo. I love Poorboys products and Blackhole is really has been awesome for me. It works great on red, black and other dark colors. I find it works best on non metallic colors. It fills well and really clarifies the paint. However Amigo seems to be as good if not better. Only thing I'm not crazy about is Amigo is to only have a synthetic wax applied after. No carnauba. Both a great value. I give a slight nod to Amigo. Either way you can't go wrong.
