I've seen plenty of mentions of Meguiars, Zaino, and Zymol on the board, but nary a message about Klasse. I used the cleaner and the gloss coat on my Porsche and was quite happy with the results. Using the same on my Montreal Blue Z3 and I am not just happy, but thrilled! Easy to apply, easy to remove, and seems to last quite a while between applications. Perusing down a few messages, I also like the California duster and the water blade that I got for Christmas. Now I just need to get some Leatherique rejuvinator to make my seats glove soft :)
