Not that I'm saying it oughta be done...but I want to add another $0.02 about the idea of polishing "beyond what you can discern with the naked eye". Heh heh, whenever this comes up it can sound soooo goofy, and elicit all kinds of "I don't care if I can't see it" type comments that just might miss the point. That's if there *is* a point because I'm the last guy to advocate doing something that nobody appreciates anyhow. But here's what I'm driving at-
Take two white cars (or silver ones...like two silver S8's

since that's how I've demonstrated this). Correct one to "perfectly fine to the naked eye" level. It'll look fine, no question about it. But then take the second one beyond that with a little burnishing/"jeweling". In decent lighting, the difference will be obvious, even to "normal people". BTDT and while nobody else thought it was worth doing, people *did* see the difference.
Want to be the guy with the "naked eye" car...parked next to the guy whose paint got burnished? That's where individual preference comes in. Hey, if you don't care that's fine with me, and as
David Fermani has pointed out, *my* Audis could currently benefit from a polishing to take them beyond their "OK to the naked eye" level. And if I were paying sombody to do it, I'd want that extra 1%. But I don't want it badly enough to polish them myself in the forseeable future :grinno:
