Because after you start fresh, you can wash the car with car wash soap, which won't strip the old wax/zaino... Then new coats of zaino will just add to the previous coats...
Yup, thats the more detailed version, and what almost all do when starting fresh each year. I just add the Zaino to the old Zaino unless there is some needed work before hand, like buffing or what not.
