No I haven't, I think I'll call Meguiar's and ask them.
I'd really love to know the answer to my questions.
I don't think it's a sealant, more of a polish with wax.
I'm sure you've seen this picture before:
From: Meguiar's Black Wax Q&A...
"We want to be sure and point out a couple of things about these two new waxes":
1 - There are no dyes or colorants of any kind in these waxes. We expect that to be a concern with the Black Wax especially, but it is nothing like that other black wax on the market.
2 - These are sort of like paste waxes in a tube; think about the delivery of toothpaste from a tube and you're really close. The tube is a metalized material so you can roll it up from the bottom, just like a toothpaste tube (which you all roll up from the bottom, right????). The wax itself has a consistency somewhere between what you expect from a true paste and a true liquid, but once you get it on a pad, either a hand pad or a DA pad, it spreads like warm butter. Both will dry to a light haze quite quickly and wipe off is very easy.

-You can use any wax on any colored vehicle, we just formulated this one with some extra polishing oils to enhance darker colors while the White Wax has more cleaners to brighten up lighter colors. Which one you truly need on your particular car is up to you. This wax does have some cleaning ability (nowhere near as much as the White Wax does, though) so you wouldn't want to apply this over a sealant or other wax as it would remove most, if not all, of that previous wax.

This would appear to answer your questions:
-Removal, or not, of a previously applied Sealant
-Is it a: Wax, Sealant, Hybrid
I could be wrong, though.
