I've been using Zymol for years. It is made in CT where I live & my chapter of BMW CCA has been to the factory many times. It is very small. If you use Zymol use one of the better grades such as Destiny or better yet Vintage. They basically have higher % of carnauba wax in them. My experience is that they hold up better, longer, & look better. Make sure you follow the application directions, ie. apply with your bare hands. These waxes are used on cars that win Pebble Beach Concours. Zymol pretty much got its start thru the Bmw Club. Gary
