Oh yeah? Well mine's black AND a wagon (or SUV wannabe depending on who you talk to).
My process sounds like a combo of all of yours. I stopped taking the car to drive thru washes altogether, even the "brushless" ones. I wash from the roof down (using a step stool to get at the top between the roof rails - I'm a little shorter than the average bear) and one panel at a time. I use car wash detergent designed not to strip wax - some odd brand I got from the guy who painted my Stude - looks like pink bubble gum color. I use Meguiar's as well though I did get a Mother's clay bar and Showtime spray. Not as bad as some people claim and cheaper than Griot's, which though good is way overpriced on many items. Use Meguiar's glaze and either Meguiar's or Mother's pure carnauba without cleaner/polisher abrasives.
Even after all that there's still a lot of swirl marks on the car. I may want to try Turtle Wax's Color Cure at some point. Will I get another black Sube? More than likely; black's the best Forester and Legacy color and the blue-black arguably the best WRX color (close with WR blue, way better than red, silver or stick of butter yellow).
Black Sube owners unite!
