Jezz JeepAlchemy, what were you doing, looking for threads you could bump to advertise for Zaino?
Zaino is a cult thing. Kind of like Jerry Jeff Walker and that other idiot that can't sing that all college kids (especially those at Texas A&M) think that they discovered as the greatest thing since sliced bread.
Zaino is a polymer wax that is no better or worse than other polymer waxes like Meguiar's Gold Class or Number 26 paint sealer. Generally speaking, when people speak of a paint "sealer", they are talking about polymer waxes which supposedly "bond" with clearcoat paints better than carnuba waxes. But I can guarantee you that there is no chemical bond between polymer waxes and your paint, any "bond" would only be a physical bond.
Polymers are supposed to last longer on clearcoat paints, hence the term "bond". However, that's only if you apply them and let them cure prorperly. Polymers must be applied very thinly and evenly to cure properly. This is almost impossible to achieve by hand--you need an orbital buffer. High heat and humidity makes the curing process even more finicky. Carnubas are easier to use because they are more forgiving in their curing process.
The only obvious difference between polymers and carnubas is the look. Polymers give a highly reflective shine that looks good on metallic paints and light colors. Carnubas give a deep, wet look that is desireable on dark paints. I actually prefer it on all paints except white.
After typing this, I decided I need to adjust my analogy between Zaino and Jerry Jeff. There is nothing wrong with Zaino, it's just no better than a dozen other waxes out there. On the other hand Jerry Jeff sucks.
