From everything I read its a opinion thing. Zaino Meguires are all great wax / hand polishes. i've got about $800 in waxes polishes and the like from over the years most are crap until you break down and get the good stuff. then Zaino / Meguires give a great look to your finish and most of the high end stuf works the same. If your looking for the great "just wax look and feel" you cant go with either. but the one thing that set one over the other was the protection of zaino. i've been a great fan of meguires and would recomend it and still use it on my other cars but I zaino'd my car a couple weeks ago and went to a night cruise driving, back on the highway at night and it seem to be RAINING bugs. and with the lincoln HID's there were even more tempted to die. Well i got home and didnt want to even look at the front end because I knew my sunday was shot for wiping bug guts off the front end. got up ... yep as bad as I thought it would be, got my "tools" out and start scrubing, decided to run a hose over it first just for grins and the bugs disapear. thats what sold me on zaino was the little added protection it provided over all the other.
