I don't think #7 or #81 (lack of cleaners / abrasives) would remove the Zaino especially given it's legendary durability.
But, it wouldn't last long at all for daily use.
I have layered #7 on top of single staged waxed show cars before a show to give it that "dipped in salad oil" look. Many garage queen show cars aren't waxed and just topped with a glaze. Mike Philips taught me that trick a while back.
Or, why don't you try Mother's Sealant Glaze (step 2). It SPECIFICALLY states that you can layer it over a wax. I'm sure trying it on Zaino won't hurt.
