Hi Tom, I have A Flex Not A Pro But I Have Had Great Results With Three Cars. Go To My Albums And Look At Pictures of My Camaro. Get A Copy Of Adams DVD Go Over It Several Times To Get Good Advice on What You Are trying To Do Then , Get After It. I Like The Plex Because It Is A Lot Faster Than The PC. Some Cars Have A Hard Clear Coat Which The Plex Is Needed For.
