Like JJU said, the synthetic "polish" type brands will last MUCH longer than "wax/carnuba" based brands. I use nothing but Zaino now. Yes, the first application will take a few hours depending on the condition of the vehicle. But, as with ANY wax/polish, initial preperation is VERY important. If you don't take the time to thoroughly wash, claybar, buff if needed, etc in the beginning, your results will not be optimum.
The synthetic based products last much longer. In my experience with carnuba based waxes, mainly Meguire's and Cherry Wet Wax, the carnuba waxes will only last a couple of washes. Where as Zaino will last dozens of washes. When I add a new coat of Zaino, I just add a quick coat of Z2 and wipe it off. It takes about 10 minutes to apply, 15-30 to cure, then 10-15 to remove.
If you compare overall time for both, you will find in the end, it will be about te same. Zaino may take a bit more time in the beginning, but requires less reapplications. Waxes may be a bit easier, but don't last nearly as long and require frequent reapplications.
My 91 is parked, and usually covered, in the garage. I bought it new in November and I did lots of buffing to remove waterspots. I lost track of how many coats of Zaino Z5 and Z2 it has on it. Anyway, I have washed it 2 times since then and reapplied 1 coat of Z2 since then.
My wifes Avalanche is parked outside and has Zaino on it. I reapply Z2 every 2-3 months to keep it shiny and smooth.
Wax/polish is just like anything else, everyone has brands they prefer. You just have to find one that works for you. I have used nothing but Zaino on all of my vehicles for the past 4 years and have no plans of changing. I would recommend zaino to anyone, but you have to find something that meets your expectations for end result and durability.
