Used it after a couple of coats of Z5/Z2 Pro after a pro detail last week where the surface was made spotless by Bryan here in Atlanta. Stuff is great, even as a topper to carnuba.
I love Z8 as a topper for a sealant, but not so much for some nubas. I tried it on top of P21S100% and it took away the nice bright, clear, glow of this nuba.
That car looks great! Great choice in using Bryan for the polishing as well. He's definitely one of the best. You wouldn't happen to need anyone to swing by and drive that car around for ya would ya (you know just to keep the fluids moving)? I'm local and I'll pay for the gas.
