Griot's makes awesome stuff. I was lucky enough to have lived near their only store in Tacoma, WA and got to go to a few car shows that they did at their place. They did demonstrations of their entire product line on the dirtiest car there. The other nice part is the buffer that they offer, I was able to put literally all of my weight on top of it and it did not scratch, scuff, or mess up the paint in any way. They make some awesome products and are pretty much the only thing I will use. As a side note, I have used just about everything on my car's, Meguiar's Mirror Glaze line, Pinnacle, Zaino, Mother's, and I keep coming back to Griot's.
