I didn't like the applicator that came with my Zaino. I'm a big fan of the smaller foam applicators that tend to come with stuff, but you just can't find anywhere.
My current favorite, flavor of the week, applicator is the little grey one that came with the EO Nano. I'd buy 20 of those if they'd just sell them. But I keep two to four good Meguiars yellow foam ones around and the same number terri applicators. I usually use the terri with a polish or cleaner, and foam for anything else.
