Griots is what I use on my SR. I also really like Griots QD, they had a huge sale at one of the auto shops on Griots and I figured I would give it a shot. Griots seems to be really soft, goes on easy comes off easy. Prep well and use the right applicators and you will have glass.
On another note is it wrong that I like to get my Z dirty in 5 minutes just so I can spend 5 hours detailing it again....
