First-time Zaino application tips

Okay, I've read through all of the directions, and I have a couple questions.

Here's what I've done so far.
1. Rinse car thoroughly.
2. Wash car with Liquid Dawn and rinse again.
3. Wash wheels with Z7 solution and rinse again.
4. Wash car with Z7 solution (cleaned and re-filled bucket, using new cloth) and rinse again.

I did all of that last night, dried the car, and put it in the garage, as it was late and I ran out of light.

Q1. Do you wash your windows with Z7?
Q2. What do you guys use to dry your cars? Towel? Chamois?

My plans:
5. Wash car again with Z7 solution (garage is a little dusty).
6. Using spray bottle with Z7 solution to lubricate, claybar entire car.
7. Wash car again with Z7 solution.
8. Mix ZFX with Z2 or Z5 and apply with a #314 applicator.
9. Wait 30 minutes.
10. Repeat #8 and #9 as desired.

Q3. I don't quite understand when I should apply Z6. The instructions say before and after every coat of polish (Z2, Z5). Does that mean I should do it before the first time I do #8 on my list?

Q4. I get the impression that Z5 is superior to Z2. Does that mean that for the absolute best results, I should not use Z2? Does Z2 do something that Z5 does not?

Q5. Same as Q4, but with Z8 and Z6.

I'm doing the GN after I'm done with the Camaro. :D

Thanks! I'm going to pull the car out and do step 5, then I'll check back for responses.

Z5 is not as glossy as Z2. Z5 is used to fill in swirls. Use Z2 for final coat.

Use the Z6 after you have the first coat of Z2 or Z5 applied. You can use Z8 if you choose. I like to use Z6 in between coats, then the Z8 on top of the final coat.

When I wash my car, I wash the windows with the Z7. In between washings, I use Stoner's Invisible Glass as needed.

I use white, 100% cotton towels made in the USA. However, I've heard the microfiber towels are really good. Some also use baby diapers.
