First, I'd personally use something other than MF towels.

I know that's an on going debate, but I prefer towels, such as those offered on
www.zainobros.com.
Here's what I'd do;
1. Wash the car with Dawn. Even though there isn't any wax, you want a clean surface, free of any contaminants.
2. While car is still wet, Clay
3. Wash using Zaino Car Wash
4. Apply one coat of Z5, mixed with ZXF. If the paint is to your standards, further coats of Z5 aren't needed. (right now)
5. Apply two coats of Z2, mixed with ZXF.
- It's recommended only three coats within 24 hrs.
- ZXF is needed to help "bond" as well as cure the polish
- Use a separate was mitt if possible. IE; 1 for Dawn, 1 for Car wash
- You can wipe the car down bewteen coats with the spray if you like.
Hope that helped?
