I use the 1Z metallic polish and I'm pretty happy with it. Goes on and comes off easy and does a great job of cleaning and removing imperfections when using by hand. I haven't tried it with a buffer yet, but then again I don't really need to. I used it before I applied the CG quick, and I couldn't be happier with the result.
