thanks... it took a hella long time to do...

i used 1z (einszitt) polishes with a porter cable random orbit polisher and various pads (about 5 different pads)... step process... agressive to almost pure wax polish. I also use a halogen lamp 12-18 inches away from the paint to search for imperfections to buff out.

i went to crevier to pick up some parts one day and parked in their lot. I hadn't wash the car for about 6 days and you know how dirty black cars get in 30 mins after they were just cleaned. anyhow, when i came back out to my car, there were 3 sales people and about 6 different customers standing around my car asking each other if it was for sale and why my car looked better then the just freshly waxed and delivered black z4 and 3 series parked 5 feet away from it... i just about dropped to the floor laughing... they said: "man thats a clean shiny car, looks better then those new cars". I replied "nah.. thats really dirty, seriously.. it needs a wash badly"

once the paint is that clear, you can tell if people leaned on it, their jackets/whatever brushes against it, etc... black is the best teacher as every flaw is shown out in the open and very obvious.
