Ok- I have yet to use this stuff and have been waiting for a group buy on it (which I noticed someone is getting together in the GB section). Here is what I got from reading the instructions that they have on the Zaino site. I will order the z7 wash, clay bar, z1 pre cleaner, z2 for clear coat paint, z5 for swirl marks. I think that is it. Now- if you want to polish quicker- the way I understood the questions is that you can use the flash cure (ZFX) to cut down on wait time and eliminate the z1. Others that have used this AWESOME product can correct me if I am wrong, but this is what I understood I would be needing from reading the instructions and tips on the Zaino page. if you have leather or plastic you want to clean they have stuff for that.
