Thanks for all the info guys. Long ~random observations/comments follow:

Edit: Accumulator, Concours and the majority of the estate wax line will have a tendency of showing your marr marks if you haven't taken them out..
Yeah, I wondered about that. The only vehicles I'd use such stuff on are the collectibles, which have imperfect (but original) finishes. Can't correct them, the old paint's too thin and I'm not gonna be the guy who required a repaint
With all the (too many

) vehicles we have around here the drivers aren't gonna get such labor-intensive treatment and oddly enough some of those are the vehicles with perfect finishes.
Heh heh, in an alternate reality I'd really like to try the Concours on my S8 but life's too short and hard enough.
Lou- Here's my current position on the W-O-W-O:
I'd heard a lot about various waxes being a bear to remove if allowed to dry. Heard it about Meg's #16. P21S, and even Collinite, but those never caused any problems for me. Still, I always liked how easy it is to do W-O-W-O with Souveran.
I'd used W-O-W-O with Souveran for many, many years. I posted something over at MOL recommending that people use W-O-W-O for the obvious reasons: people say it's a paint to buff off if it dries, W-O-W-O is recommended by the manufacturer, and it'd always worked well for me. Mike Phillips challenged me on the point- he pointed out that I never use W-O-W-O with my other waxes and said I oughta try letting Souveran set up. He said he's experimented with a *lot* of waxes (hey, it's his job) and never had any problems from letting one dry as long as he applied it properly thin.
So...I applied it to some areas on my wife's A8. Let it set up for varying lengths of time up to 90 minutes. In every case it buffed off easily, looked great, and might've even lasted longer than it does when W-O-W-O'ed.
Not saying there's anything *wrong* with W-O-W-O, hey, I have over a decade's evidence that it works great. But it does occur to me that there could reasons other than functionality behind the maker suggesting W-O-W-O, especially if letting it set up results in greater durability.
More of Accumulator's Autopian Heresy: You guys who find it therapeutic/relaxing to detail cars make me feel a zillion years old and very stodgy

For me, detailing a car is like sharpening a tool...a chore I have to do as part of proper maintenance. I do find it rewarding, like any other job done well, but it's just not my idea of how to spend my time. And to think I used to really *love* doing this stuff....
