What don't you Zaino on the 8?
 

First time waxing. Do I apply Zaino to the pillars, windows, side vents, and the black exterior by the rear accent?

DO NOT apply Z2 (or Z5) to them, but you can use other Zaino products: For the pillars, side vents, mirror bottom/sides, front grill, wheel wells, and rear black you can use Z16 (perfect tire gloss) or other non Zaino products like 303 Aerospace, Back to Black, Vinylex, etc.

You can use Z6 on the side and rear windows, if you want to.

I don't Zaino anything that's black plastic on the exterior (the bottom of the side mirrors, the front grill, the side vents like 6speed8 said, etc.

I DO apply it to all glass, the wheels, the tailpipes, the lights, and all painted surfaces.

I don't wipe it off the wheels and tailpipes- it's easier to clean later if you have a layer of Zaino to wipe off under the grime.

Thank you. I have the entire Zaino kit. I will try the Z16.

I will wax the wheels. They seem to take the longest to clean on the entire car.

You can use Z6 on all the windows, including the windshield. It acts like RainX and causes rain to bead up and roll right off as you're driving down the road. Plus, it's MUCH easier to apply than RainX.
