I'm really satisfied with FF, but I've never used Zaino. From what I understand they're equal in most ways, except FF last a couple months longer. But I'd definitely like to hear from people who've used both.
I used Zanio on my 98 Civic HB and FF on my 97 Rav4L, both vehicles were black and FF wins hands down. FF also was voted best paint care product in Corvette Fever May 99 issue and they also liked Zaino.
i've only used FF but you know what tey say, if it isn't broken don't fix it. i'm pleased with the product and it came at a reasonable price, so until something AWESOME comes out, i'm more than happy with FF =)
Thanks guys for all the info. I like my paint as perfect as possible, so I'm really a sucker for "great" products. You have raised my curiosity to the next level, so I may have to spring for some of that FF, when I run out of Z. After all, years ago I thought Meguiar's was the best. Obviously, both Z and FF are years ahead of most of the competition. One other thing, the best product I've ever used to clean the paint was Meguiar's clay bar. I used it one time several years ago and my paint has been as smooth as glass ever since. Regardless of brand, the clay is essential for flawless paint finishes.
