Dammmittt,
If you are looking for detailing ideas, procedures, discussions, reviews, and advice, I recommend stopping in at
http://www.autopia.org/ Lots of good advise there. It's hosted by Autopia Car Care, but isn't terribly commerical.
While I like my bimmers looking nice, I'm not anal about it. I would stay away from dish detergent because it
isn't good for your paint. I use Sonus and Klasse products to keep my coupe looking nice, and tend to side towards protection rather than pure out and out beauty.
