Running around saying "ZAINO SUCKS" with no sort of argument to back it up is just plain ignorant. If my carpenter told me that the wood I had picked out sucked and didn't tell me a better type of wood or didn't explain why it sucked, he wouldn't be my carpenter for very long.
Maybe his paint is "the best" because he plonked down $$$$ for that expensive stuff? Ford paint (on the Contour at least) sucks. Comparing aftermarket paint to stock paint is not apples to apples.
I bought my Zaino supply from a detailer that was leaving his shop and moving on to sell cars (what's that? a detailer that uses Zaino??). Sold it to me at wholesale price, which is the only reason I bought it really. I was happy with Meguiar's and didn't think anything could be better for the price I was willing to pay. I threw the Meguiar's away when I moved last summer.
