I have tried Zaino and I have to say I couldn't really tell any visual difference from the Meguiars products I've been using. Zaino does last longer though. But applying Zaino just takes way too long so I think I'm done with it. I've been using only Meguiars products on my car lately - specifically the #26 High-tech yellow wax, #7 show car polish, and #9 swirl remover polish. I think my car has a great shine, but I would like it to have a deeper black color when it's in the sun. At certain angles it will look kinda yellowish, especially on the bumpers which were just repainted about 6 months ago so it shouldn't be fading yet. So what products will enhance the color of my car and give it a deep black wet look?
