If you wash a car with Dawn Ultra to get off the current wax and then clay it, which provides more protection? A) Adding a single layer of ceramic wax (like a Turtle Wax or Meguiar's) or B) washing again with a Meguiar's Wash and Wax and then adding the ceramic wax? I'm wondering if the weaker wax (wash and wax) would allow the ceramic wax to break free easier or if having two coats (one with wash and wax and then the other with ceramic wax) adds more protection?
