Forgive me if this has been asked before, I tried searching but I don't think I utilized it properly, I ended up sifting through countless posts with no avail. Anyways, I've been told that layering a coat of carnauba over Z2 or Z5 will simply strip the Zaino. The guy who told me this is EXTREMELY pro-Zaino and completely biased towards anything else. In fact, his exact words were "don't layer any carnauba wax over Zaino, in fact, that sh** will strip it off Z2." Is there any truth to this?
