I didn't think the Zaino was difficult at all to use, just a pita to do three times. On the other hand, it lasted a good long while (6-8 mos), made keeping the car clean a breeze for all that time and I've never seen anything level, shine and protect the paint like that. I could wash bugs off the front with a hose and the car just didn't seem to get as dirty, like it was repelling the dirt. What's your choice?
