I probably have about 3 coats of Z2 on my car. I would like to remove it and try FK1000P. However, because Zaino products don't seem to be like a carnuba wax (I think they are a polymer) I'm not exactly sure what is best. Is just washing the car with Dawn Ultra enough? I've read about doing an Isopropyl Alcohol Wipe, but I get a little worried that is too aggresive. Can anyone suggest the best way to be sure I completely remove the Zaino so I can start back fresh?
