Hi I've followed the whole paint prep procedure for my newly aquired zaino system (dawn wash, Z18 clay, dawn again, dry, polish out swirls and scratchers, dawn one last time, Z7 wash, dry completely, inspect finish, let dry overnight in garage.) Now it seems that I'm ready to start with my first layer of Z5/zfx but I was wondering if you apply Z6 before this layer or just in between layers? I've read up on the board and some say you do, but the zaino website has no mention of this. Please help this first time noobie detailer out. Thanks
