I've been using Zaino for several months now. First on my son's 02 Firehawk & 68 Firebird. Now on my new baby. The initial process is pretty labor intensive. You have to wash with Dawn dishwashing liquid (which strips off any wax on the car), then you apply the Z2 treatment, wipe it off and then apply the Z6 gloss enhancer. It's easy to apply & remove. All that's needed is 2 or 3 applications of Z2 over a period of a couple of days. After that you just wash with Zaino car wash, dry, apply a mist of Z6 & wipe it dry again. The paint is protected from acid rain, bird doo & all manner of nasty stuff. And the gloss is awesome.

With all that said, Crystal Guard sounds like a superior product. Wish I'd known about it before I put Zaino on. :x May take the Zaino off & try it.
