Ken800,
How many coats of Z2 are you going to have him do?
I did not use ZFX so it took an entire day (85 degree temp) to apply 1 coat and I did not claybar, just used Dawn. I waited about 2-3hours for the Z1/Z2 to dry. Over the course of the weekend I added another 2 coats of Z2 and Z6.
I know ZFX is faster since you don't have to wait as long between coats.
Using ZFX, I would not expect more than 4-6hrs to wash, claybar, Z1/Z2 and Z6. Z6 is just the gloss enhancer so it goes on in a few minutes. Spay on, wipe off.
