Zaino Z-9 & Z-10

Anybody tried the Z-9 and Z-10 for the leather in our cars? Are the seats in our cars even leather? I'm pretty sure the back seats are just high quality vinyl but I don't know about the front.

I've used it on many of the cars I detail, but never on my GP....that stuff is much more pricey than other leather condioners out there, and our leather is nothing special anyways, my seats aren't even real

This thread is incredibly old. But for anyone that wants to know the Zaino leather stuff works great on my 06 seats. I also use the conditioner on the dash. Works very well IMO. My dash was kind of "ashy" looking. Looks much better afterwards.
