"I've been a faithful Zaino user on multiple cars (a Ford Expedition and a Lexus RX400h) for over seven years. I was THAT guy who would have friends over for a 'Zaino Party'. We'd apply coats of Zaino onto each car in a staggered fashion so we could remove a coat on one car while another was drying. My typical treatment would include a coat of Z-5 (w/ZFX), then Z6, then Z2 (w/ZFX), then Z6, then a final coat of Z2 (w/ZFX), and then a final spray of Z6. After every wash I would use Z6 to bring back the shine. I drive to Tahoe every single weekend in the winter, so this caused me to perform this whole process twice a year. It took me about five hours with the Expedition, three with the Lexus.
Now, since being introduced to Tech Shine, things have changed. My vehicle stays shinier longer, and it repels dirt for a much longer period of time. For example, my average Tahoe drive used to totally coat my car after one trip with Zaino. With Tech Shine, it takes several. On top of that, if I take the car (by mistake) to an automatic or poor wash facility, my car appears to retain less scratching with Tech Shine (the dirt just doesn't seem to stick as much). With Zaino, after two to three post-Tahoe washes, I started to see some serious imperfections (hence why I used Z6 after each wash to keep up).
But enough with all of that! One wash with Tech Shine and it looks like I spent hours waxing, the shine and comes right back to a perfect finish - high gloss - no swirls even after collecting a MONTH worth of Tahoe cement. You just wash, spend five minutes applying Tech Shine, and done. Enough said. Sorry Zaino Bros."
