Cool link. Very helpful to actually see it in action. I wonder how many times can youcan "level" your paint before you'd remove all the clear coat?

Thats a controversial subject, I've heard that polishing once a year for 20 years would still not remove enough clear coat to wear thru to the paint if using a fine machine polish...using something like a #2 or #1 machine polish would probably shorten that. Technique would play a role, someone not knowing what their doing could bear down too hard using an orbital(non-random action), or do it too often (once a month?) :dunno: I asked a detailer that was visiting Griots one day and spoke to him for an hour..he chuckled when I mentioned that wearing thru the clear coat with a random orbital...if you ever own one, you'll see what I mean, you can stop the pad easily with your hand, thus, you cannot bear down too much pressure on the pad or the random orbital action ceases.
High points on the "hips" of contours could potential wear thinner than straight flat area's, but again, that was a concern in the days of strictly orbital polishing. Random orbital prevents heat build up on these high spots.
I certainly wouldn't be real concerned with wearing out clear coat, unless you use a real cutter machine polish consistently, which you wouldn't need to do.
My 2 cents

That was great Rip. I'm going to use my PC for the first time this weekend and seeing a demo came in handy ;)
I have a question though... He kept buffing until the polish is almost all off. He doesn't let it dry... Is that OK with the polish he used? Do you do the same thing when applying Griot's Machine Polish #3?

I think he spent too much time in one spot, but then again, he was 'cutting' that finish, apparently the method he's using would be in a scenario of a "not so well cared for" finish..ie, it needed some work...I've only polished this bimmer once last fall, and my method (suggested by that Detail guy that was visiting Griots) was to polish to the point that the polish just started to dry, 2 ft. by 2ft. sections at a time. Then I would shut the PC off (KEEP THE PC IN CONTACT OF THE SURFACE WHEN YOU TURN IT ON AND TURN IT OFF! or you'll end up with polish splattered everywhere.) and wipe that section dry, move onto the next.
