I'm a Zymol man. I don't know how anyone can say Zaino is easier to use...If you follow the instructions, Zaino takes 6 working days to complete with all the drying time and multiple coats. To heck with that!
If you follow the Zymol directions (I am sure most that don't like it don't) than you wipe the stuff off before it even dries and becomes hard. No way can you beat the speed and effort factor of Zymol with Zaino (which I have used on multiple occasions, for the record).
There is a trick to get the ease of use and even shine of Zymol that I am positive that those who don't like it didn't do:
After applying the polish over an area, wipe just the bulk of it off and don't try to hand polish it perfectly at that time. Do the rest of the car. When all done, wet one clean towel pretty well and wipe the car down with the wet towel so that it leaves little beads of water. Then dry the car with the other towel. This is an incredibly easy step.
Wa la, a car that looks like edible liquid candy!
And you saved money, didn't join a cult, saved 5 63/64 days, and have a car as shiny as the exhausted Zaino guy next door.
