I <3 Black Granite Metallic. First wash with meguiars hyper wash, worked so much better than the neon green crap from Walmart. Also tried meguiars spray wax, I think it worked really well. Not as good as a proper synthetic or carnuba, but far easier. Entire wash and wax took ~90min.
I did notice a nasty chip in one of the headlights though :(. I really hope that's coveredby warranty, it's pretty bad...I'll post a pic in reply.
