I have used two synthetic chamois for 20+ years without any problems but decided that I needed microfiber drying towels so I got a 3 pack of Cobra Guzzlers. After a hard two step correction on a friend’s super swirled black Infiniti G37, I washed it to remove polish dust. After blowing off most of the water, I used the Guzzler to remove the remaining water. The sun was shining on the side as I got the last water drops and I watched scratches appear when I wiped. I walked back around the car to inspect and they were all over the car! Back in the garage for a 3rd Step with a black foam pad. What should I have done differently? Never owned a black vehicle and probably never will. Thanks!
