I have done all steps: dawn,claybar,z-7,z-6,z-5,z6,z5,
z6,z2,z6,z2,z6,z2,z6,z2,z6. Car looks great. Under select
lighting I can see scrathes, very small but over the entire car.
Is there anything I should use, or can I use z5 and then go
back to z2, or do I have to start over with dawn.

 

The thing about Zaino Z5 is it does not remove scratches just cover them up optically. By using more coats of Z5 you will reduce the visibility of fine scratches. It may take anywhere from 3 to 10 coats of Z5. Just remember to finish up with Z2.

 

As William said, continue to use Z-5, if they are fine scratches. And no need to use Dawn. That was just a one-time thing, to remove carnauba wax and oils that may have been present on the car
