You do realize those are kits with multiple products and not just one product, right? That said, no you don't want to use Zaino sealants on top of Meguiars polishes or waxes. The sealants won't bond due to the oil content of the Meguiars products.
CS is able to work over carnaubas but I still wouldn't recomend it. Use your Megs polishes and do an 50ISO/50water wipedown to remove the oils and use the Zaino sealants. I'd reccomend the ZAIO/CS/Z8 combo.
