Check this post out (it was long so I just pasted the main idea)-->
"......Another wax test done by someone who knows nothing about car care, what a surprise. I was in the detail business for 15 plus years, as many people know I was a partner in the largest detail chain in the US, we were Meguiar's largest end user of products for 5 straight years, over a 15 year period we tested hundreds of products, we tested durablity, shine as well as ease of application...........
......I find it very funny that Zaino came up at the bottom of your test, you either did not have a clue how to apply it, or were applying it like a carnauba wax product. Zaino may not outshine every product after a coat or two, but there is more to a product than just shine alone, and shine is a very subjective thing, some people like the oily look of carnauba's and some do not, I believe that my customers like the shine and durablity that a synethic product like Zaino will give you. The internet is a great thing for sharing info, but it can also let any moroon with a camera and a keyboard spread a pile of bull**** that has no scientific value at all........"
