So, Z6 is just like QC. I got it.
and for the Z-PC part. Yes, it was really really PITA.
I applied it by hand. Front to back and up and down motion for entire car.
I waited about 30 min. and buffed.
That shit wouldn't buffed easily. It was hardest exercise I've ever done.
but! it was really worth it. it moved most of fine swirs and some scratches.
after that, Z-5/ZFX was pretty easily buffed.
You really need strong arms to Zaino your car.
