SSR 2.5, yellow cutting pad, PC set to 5: Jeff's Werkstatt Prime, white polishing pad, PC set 5: Jeff's Werkstatt Acrylic Jet, black finishing pad, PC on 5. Multiple coats of AJ were required as there were some HEAVY swirls covering the paint after I removed the first coat. As with the Z4, the AJ was a bit tough to remove even after knocking down the thick spots with the PC - It took so much elbow grease to get the AJ off that I know I put the swirls into the paint myself by bearing down to hard with the microfiber towel. I suspect that this is due to the non-abrasive nature of the black finishing pad I used, as I switched to a white polishing pad for the next two applications and had none of the trouble, and the reflection started becoming extremely clear, wet-looking, and reflective after the second coat. I then topped it with a third just for the hell of it. All in all, I am happy with Jeff's products.
