I used Klasse all in one and the sealant on my 2007 328i jet black four times a year and it looked great and protected the car for years with and without a garage. Based on those results I started using Klasse on its replacement a jet black x3 35i. Jet black is my favorite color but it is tough to keep looking good and the Klasse helps. The all in one is easy to apply and remove but the sealant is a bit tougher to remove. I also use a clay bar one per year. The all in one helps to hide/remove swirl marks common with these black bmws. So for me the Klasse has provided protection and shine across all weather and environmental experiences.
