I have a question..

Do you always have to apply some drops of ZFX to Z2 to apply just one coeat of Z2?

or

Is the ZFX drops only used when you want to apply multicle coats of Z2 one after another.

 

The ZFX is for fast cure, allowing the extra layering in 1 day. If you only intend to put 1 layer on, then yes, you can just apply the Z2 without ZFX, but that's only as long as you're not starting out with the first coat of Zaino on the car. As long as you've got some on there prior and used either Z1 or the ZFX with that, then you're fine to just apply the Z2 by itself, allowing 24 hours before you do it again (if you intend to).

 

Thanks for answering my doubt.
