I've got midnight blue but never used the Z-PC. In the right angle under bright sunlight you can see very light swirl marks.

When you apply and remove Zaino don't use a circular motion. Use up and down and side way movements depending on the direction that light will hit the car. Hood from the windshiled to the front and doors straight up and down and left and right.

Be sure not to clean your towels using fabric softene. You'll get a lot of smearing if you use softener. I use heavy weight micro fiber towels. I do not like using the light weight cotton towels they don't remove the Zaino as well

You must live in a very humid place. I have never had to add the accelerator to
Z-5 only the Z-2. The Z-2 is easier to remove than the Z-5.

If your car is hazing you've got too much product on it. If you are spraying on the shine enhancer (Z-10?) be sure to apply it to a very small area and remove it quickly with a heavy micro fiber. If you don't you will get a haze.

Finally, I would think you should rewash the car with the Zaino Car wash and start over with Z-2 or Z-5.
