Mike the Zaino Z6 is great detailing spray too. I use it after I polish the car and after my weekly car wash. One note about both Meguiars and Zaino.....their customer service is second to none. Always available by e-mail to answer a detailing question and they back up there products too. Acrispy 1 had a problem with a Meguairs product last summer and when we were at Carlisle they (the Meguiars folks) could have been nicer, made me feel guilty for using Zaino. I have used Zaino's car wash and I find the Meguiars Gold far superior, that's all I use. The thing I like so much about the Zaino Z-2 polish product is how easy it is to use, and there is no dust when you buff it off. The Zaino AO1 does leave a bit of dust but nothing like the other wax/polish products I've used over the years. I use that product followed by a coat of Z-2 and then the detail spray several times a year. Monthly it gets a coat of Z-2.
The main thing is keep your car as clean as possible and always polished. There are two Crossfire's in my immediate area that are not well kept and they ain't pretty. I'm talking caked on brake dust and it looks like they get washed maybe. No matter what you use keep em' clean.
