The Zaino site has a suggestion that you apply the Z2 with front to back strokes on the horizontal surfaces and up and down on the vertical surfaces for a bit of extrra pop.

Other than what everyone else said.

Look carefully at what your eyes and brain "see" but you filter out. For example, on my XKR, you can see a glint of exhaust pipe and the edge of the muffler in each rear wheel well. I make sure all those things are clean and shiny. It makes a difference.

Pay particular attention to door, trunk and hood jams.

You won't be able to vacuum on site. Take a roll of duct tape. Wrap a good amount arount your hand and lightly dust carpets and fabrics. Works much better than a lint brush or roller.
