Like the other guy, I use Klasse. A little bottle lasts a long time. I renew it every 4 months or so and sometimes cover it with a layer of paste wax. But I have had the same problem with wax on the moldings. In the future, I'll probably stick with Klasse only, since it's simpler and looks about the same as a good wax but with no molding problems. The carnauba on top of Klasse gives a slightly deeper shine, but it's hard work.
