I started out my Adam's detailing projects with the Porter Cable on my 08 Z06. I found that I had really work at it to get the paint to a point where I could move up to a finer grade of polish. Plus my hands were going numb. My son bought me a Flex for Christmas and man, that really got the job done much quicker. Just wondering, any other members notice the clear coat on a Vette being harder than most other cars?
