Does it matter if one applies the Zaino in a top to bottom movement on the sides and boot, front to back on the top and bonnet or is circular application OK?

I spent many hours yesterday and today applying several coats so I had plenty of thinking time.

Does it really make a difference in the outcome? I tried to stay with the technique described above but found myself using all of them at various times. Any input will be appreciated.

It turned out fantastic. The best she's ever looked,after 22K miles, even with several blemishes on her face.

 

One of the first things i read was not to wax in a circular motion. Any scratches you get doing that will be more visible than if you go back and forth.

 

I tend to wash,wax and quick detail front to back on the bonnet,roof and sides,up and down on the hatch.Side to side on the bumpers.

 

Our Zaino dealer in Charlotte has recommended:

Front to back along the hood and roof.
up and down along the tailgate and sides.

He describes this process as producing better optical qualities in the finished job, yet I suspect the real reason is that any inadvertant, fine scratches in the clearcoat will be less noticable.

This is an excerpt from the Zaino official website www.zainobros.com which says spread it in a circular motion, then go back/forth, up/down to actually apply it. I use the same back/forth, up/down motion to buff it, and when applying Z6 or Z8.

ZFX™ Enabled Show Car Polish
Follow these easy steps:

1. Apply Zaino Show Car Polish enabled with ZFX™ with a 100%, made in the USA, cotton applicator. Use the polish sparingly. A small amount goes a long way, and you will be applying multiple coats.
2. Squirt a dime size dab of polish on your applicator and rub it into your paint using circular hand motions. Then, go over the same area using a straight back and forth motion on top panels and an up and down motion on side panels. Allow the polish to haze over (20 minutes is sufficient).
3. Buff off the Show Car Polish residue with a high quality, 100%, made in the USA, cotton detailing towel.
4. After buffing, spray the car with a light mist of Z-6 Ultra Clean™ detailing spray. Z-6 will help buff away any remaining residue and enhances the brightness of the finish. Using Z-6, the next coat of Zaino Show Car Polish will apply even easier.

 

Yep... on the hood and bonnet, go front to back (or back to front). On the vertical surfaces, go up and down.

You can't avoid doing some curves... The car has edges and curves, after all... maybe if you were waxing a Scion Xb...
