If you guys read the statement again you will see that they recommend using the Dawn BEFORE applying the Zaino. That's to make sure existing waxes are removed. The Z-PC in my opinion is the same thing as Duragloss #652 Pre-Cleaner #2.
OP, in summary:
- Polish the Zaino away and make sure to have extra pads on hand in case they are needed
or
- Use a dedicated paint cleanser - Pinnacle, Wolfgang, P21S, Dodo Lime Prime or Lime Prime Light, etc.
or
- Perform an APC wash
Note that a body solvent may be necessary.
