Yesterday I used Menzerna IP & FPII on my car and toady I was going to follow it up with Zaino. I have Z1, Z2, and Z5. I know to use Z1 first, but directly after using Z1 can I use Z5 or Z2? I still have a fair amount of scratches on the car, should I use Z5? If so how long do I leave it on before applying Z2? Thanks!
