I have been using Zaino products for about 2 years, the slickest finish I have ever seen, I heard about it from some guys in my club Mustangs of East Texas. Its expensive and you can't buy it at Walmart, but worth it! Every time you apply the Show Car Polish the shine gets deeper!
I have bought it at Car Shows and Swap Meets, but you can get it online at
http://www.zainobros.com. You will never go back to Walmart for waxes again.
