I'm very impressed with the shine. Maybe it's because I haven't seen the car all winter or that I buffed it, but the Zaino seemed to shine the hell out of it more than anything I usually use. I've had the Zaino for about 2 or 3 years and have only used it maybe 3 times, but I thought I'd try it this year. If it lasts as long as all other waxes/sealents/whatever, then I'll keep using it.
