After reading about Zaino everywhere, and the fact I have some Christmas cash, I was thinking of making the plunge. I guess my problem is after buying Z2, Z5, Z6, Z18, and ZFX, I spent a total of $83.70! My wife is really reluctant to let me spend that much on car appearance stuff. I guess my questions are, how long does the "starter kit" last? Will that purchase last me a few years? Or does it get used up quickly because of the multiple coats? I do see my wifes point since I do not know anyone locally that has used Zaino. Thanks for any assistance/info you can provide.
