What color is your car?
It typically takes about 4-5 coats of any combination of Z2 and Z5 to get teh dramatic results that make people go
when they feel the paint.
During warmer weather I typically wash and Z2 every other week since it's so easy to use.
After 5-6 coats, I would recommend the average user probably only needs a coat every 3-4 months to maintain a nice shine.
Just be sure to use the spray after each wash and the surface will still look and feel amazing even if you don't apply any Zaino for an extended period of time.
