I do a car a day with Polymers. On good paint use a Festool Rotex Machine set on 2 - guaranteed no swirls in writing by the company. Step 1 use a White Waffle Pad loaded with Festool 8000. Take your time. Next, change to a Black Waffle and load with Festool 11000. Remove both compounds dry then lightly mist with water and go over again with Microfibre Cloths. For that BAM! factor lightly spray Showroom Glaze a panel at a time, wait ten seconds, remove with a Zymol or Mothers Microfibre. Go back to the first panel, lightly mist with water and go over very diligently. Keep SG off the plastics! They ready Hotrods for Shows this way over here in Oz.
