Had nice weather this weekend. So I decided it was time to start the Zaino. My roomate had some and was out of town. After reading some instructions I realized that he didn't have any z5 left, so I used z2 instead. The Z looks great, but when I get more z5 do I have to start over? Do I need z5? I just went from z2 to z6 and repeated..

 

You don't absolutely have to use Z-5. It's main purpose is to help hide fine scratches and swirl marks that most cars pick up over time.

You can apply a couple of coats later if necessary. I put some on as my first layers then again after about 3 months or so. There is no problem mixing layers of Z-2 and Z-5.
