I love talking about this stuff. I can't take all the credit of my line of products, I private label for several professional detailing supply companies that are not available to the public. as far as side by side comparison it has already been done. go to
www.gurureports.org this is a panel of professionals in the industry with no ties to any company, the bottom line is the Synthetics dominated over ALL brands/types of wax. Here is a tid bit of info you will find interesting. Zymol has been mentioned several times here. One day I did some detective work wondering how a company could sell jars of wax from $9.00 all the way to $1,300.00. Did you know the Blue bottle of Zymol cleaner wax that you see in K Mart and Walmart for 9 bucks? Guess what? The address on that bottle is Turtle Wax headquarters in Chicago. Its completely legal, but the end result is the consumer thinks they are buying one thing, but they get something else. Gary
