I've used both Klasse and recently, Mcguires (2-26-34). I ordered the Klasse from CA and it was very expensive. It did give my cars a great shine, however. I just started using Mcguires formulas and am happier with them than the Klasse. For one thing with the Klasse after a rain, the car is full of water spont. With Mcguires, the water beads up and dissipates leaving no water marks. I did boo-boo this week, while out of town, and parked under a tree all night. THe birds had a party on my MB. Unfortunately, the doo-doo did not bead up and dissipate quite as easily!
