I have been detailing since i was 16 and now 35. I have used almost every wax/polish out there. From cheap to very expensive and i have to say that Zaino is hands down the longest lasting and best looking. I will admit that the first application does take a while if done correctly! But results speak for themselves. I do my Pathy and all my vehicles 2 times a year with 3 coats of Z2 with the flash cure. The more you put on the longer it will last, but only 3 per day.
Here is some food for thought. When wax is applied to you car you think that you are getting protection, but from what, dirt, uv rays, water marks? Sure it looks good and the car is shiny, but as the car sets in the sun the wax softens, thereby letting dirts/dust stick to it. Then you park in the garage or it gets dark and the wax hardens back up with the dirt/dust still in it. Now you pull it out to wash it, oops you are rubbing all that fine dust into the clear of your car. Now you have what we call spider webbing.
Think about it!
So my advise is to never use a wax, always use a polimer polish that bonds with the clear.
