What Macgirl said :xyxthumbs *I* didn't find the fillers/waxes/oils in 1Z stuff to be a "problem" at all. They're NOT like 3M SMR where the filler-effect overshadows the abrasive effect, leading to swirls that seem to "come back". Rather, the 1Z's "extra ingredients" just make them easy to use, make things look nice, and impart some protection. You CAN achieve a flawless finish (totally marring free) with 1Z polishes.
If you're gonna apply Zaino, or maybe even AIO/SG, that could be different (why use a product with fillers/waxes/oils just to strip them off?), but otherwise it's not gonna be an issue.
And FWIW, *I* just LOVE the look that 1Z's polishes (I use PP then MP) impart to metallic paint. Just top with your favorite Last Step Product, and you'll be all set. And if you want to wait until the next wash to do the LSP, you'll still have some protection.
