I was using Zaino for about a year and was somewhat happy with it. It goes on and wipes off pretty easy and left a pretty nice glossy shine behind. What always had me scratching my head was whenever it rained, the Zaino would only bead up on that initial rain shower. I would wash my car when the weather got nice and the water just didnt bead up like it should. I kept using Zaino until recently when I just got tired of the multiple coats and steps you put into it, so I went with Meguiars Gold Class paste wax, even after multiple rain showers the water still beads up and rolls off, and when I wash the car it beads up. The after multiple rain showers or washing's the Zaino always left a sheat of water, or the water just didnt bead up like it should. It has me questioning if the Zaino was still on there or not. I know its supposed to last longer but I just didnt find that to be the case, plus the Meguiars leaves a shine that lasts through multiple washes, the Zaino was shiny after application but after a week or two it was back to the regular finish. Any explanation for this?? I will say that from now on Ill probably just use Meguiars wax because of the shine and water beading ability.
