In your opinion does Z5 really cause much difference in filling in minor swirls and scratches? I wonder because I can still see some swirls in my SB after several layers of Z5. Maybe some swirls and scratches are inevitable with a black car. Should I just focus on the maximum optical shine and stick strictly to Z2?

Regardless, thanks everyone for hooking me on Zaino, I really have learned a lot on this board.

 

I used Z-2 I have alot of swirls. but I attribute them to my using less than good towels, often not even 100% cotton, or if they are, not made in america.

but Im switching to Z-5 to try and save it. but the good towels are just too expensive to justify.

 

i use z5 only and i can verify that it does get rid of swirls and scratches.. i had some clearcoat scratches off the showroom floor and a few coats and they were gone
