But here comes the fly in the ointment. Zaino is awesome HOWEVER, Zaino will exacerbate your minor swirls or any other imperfection for that matter. Therefore, if you want to use Z5 then you'd better do some serious correction with a polish first. You need to apply Zaino over a corrected finish or those swirls and cobwebs will show right through. That goes for Z5 also. Don't believe the hype about Z5 filling minor swirls.
Not to totaly disagree with you here as I am no more than just a guy who likes to keep his car clean. This is my 2001 Mustang of which I used Zaino on in 2004. Prior to that the only detailing it had ever recieved was regular washing, and a coat of Zymol every 6 months or so. Before the Zaino there was noticable swirl marks in the paint, nothing major but enough to say that Zaino will cover them.
Below was all done by hand with the older Zaino(not the pro)
Washed with Dawn.
Clayed car
Wash with Z7 I think whatever # their wash is.
Z2 w/ ZFX
Z5 w/ZFX
Thats it, no corrective work done at all. This was my daily driver and was never parked in the garage. Here is the close up, every incho of the car looked like this, the wavy line in the middle is just a refelction of the outline of my knuckles holding the camera.
Here is the front showing the reflections of the clouds and trees. Don't mind the front bumper or the Headlights I had the bumper re-painted about 4 days after this and replaced the headlights as well.
