I just used my flex for the first time. Just practicing right now as I have never machine polished. I started with Optimum Finish and white ccs pad and saw a slight difference then I switched to Opt Finish + orange pad and saw a big difference but still felt it needed more as this car was beat up. As I grabbed my bottle of Opt Polish II, I had these questions I wish someone could have answered for me. 1. If I am moving to the Polish should I go back to the white pad (LC ccs) or stay with the orange? I stayed with orange. 2. Can I use the same orange pad with the polish as before or should it be a fresh one? 3. When do you decide if it just needs another pass of the polish or I need to switch to a compound?
