I usual do a conventional wash once a week, but during the week I will use the touchless "Luster" laser wash...which happens to be directly across the street from my house...so it's pretty convenient! My question is about the soap that these car washes use...are they harsh...will they harm my coats of Zaino polish? They also offer a "color clear coat protectant" option...anyone have an idea what that really consists of? When it sprays on the car it is a foamy multi colored soap...if that helps? What about the "Spot free rinse"...what is in that stuff?
