I just bought the Zaino car wash Z7, Z2, and Z6. Do I need ZFX to be able to use these products? It says it helps the the polish cure faster? Cna anyone tell me if you have used thesd products without the ZFX, or would I be stupid to use them with out the ZFX?

the zfx makes drying time much much quicker for the z2 and z5. its not necessary but recommended. you bought all of that, might as well get the zfx. the process takes a full day with the zfx, it'll enable you to do 3 coats in one day. without, you might be looking at a couple hours drying time. the z7 is car wash and z6 is detailer spray- zfx is not needed for that, only for use with the actual polish.

ZFX is needed for the first coat. It helps it bond to the clear coat. After the first coat, you no longer need it.

With Zaino you either need to use Z1 or ZFX.

Z1 is only needed on the first coat. Otherwise you can use ZFX with any of the other products because it essentially takes the place of Z1. ZFX is highly recommended as it decreases drying time.
