Nice video link...I've never heard of Adam's stuff though. He mentioned some good points. But, I really hated the fact that he touched the paint with his greasy hands! The Porter Cable is the tool to get for enthusiast detailers. I laughed when he said that the Porter Cable does not spin...of course it spins! It spins 360 degrees, and then oscillates left and right to reduce the heat build-up capabilities of the machine, making it very difficult to burn paint.
