I used the Meguiars 3 step kit on my white Wellcraft this past weekend- it worked extremely well with my Porter Cable 7424 and Griots pads! I could not believe how well the oxidation remover worked, just follow the directions (that is a challenge for me at times) and don't let it dry before wiping off. I also bought some lambs wool velcro pads for the Porter Cable- beats removing wax with that cheap buffer I used to use!
