When I first got my Titanium Silver 328i I used Blitz Wax(which didnt last long). I then switched to Mequires#26. It worked OK but I've never been thrilled with the way the paint looked. This weekend I tried Griots Garage Fine Hand Polish followed by Griots Best of Show Wax. The results were incredible. The gloss is perfect you cannot see any hairline scratches/swirl marks!!! I've never had a wax make such a dramatic difference. If you want to try this out you can get a catalog at 1-800-345-5789 or www.griotsgarage.com. Hope this helps
