pungo the old school (Turtle Wax, Kit, etc.) used a very small percentage of carnauba in their products. They also used a lesser grade carnauba, fast forward to today and you have all sorts of percentages and grades used in the production process. Add to that various sealants and you have a mix of products that vary from totally extreme and sublime to the laughable. Zymol e.g., in the US is not the same Zymol made in Europe. In fact, Turtle Wax makes the US version and it is barely a whisper of the real stuff. So what you see isn't necessarily what you get. I was a firm believer of the synthetic products for years. Klasse and Zaino products filled my storage cabinet. That was until I bought a Z4 with black paint. Then I noticed that there was something lacking. I tried a dozen different high grade carnauba products, all had okay results. Okay meaning that the usual features were there but none had a snap. Zaino looked like the saran wrap/plastic shine that I mentioned before. I tried many combinations with products both synthetic and natural. Then I was given a new product called Wolfgang Fusion Concours. This is a high grade carnauba wax...a very high grade. Preparation is the key to any car care treatment so I when the extra mile with the prep work and then applied the Wolfgang wax. It is a wipe on/ wipe off wax, I applied with a Porter Cable. The results were stunning. Not only did I have a shiny polished car, the shine had a depth and a snap I've yet to see from another product. I was impressed enough to endorse this for our Z4 black exterior painted vehicles. I use the product on a regular basis (I did the same for Zaino) on my cars because I enjoy keeping my cars looking and ready for a judged competition because they are judged all the time: by me. Long lasting protectants are products perfectly suited for the driver that only occasionally polished their car and that is were a product like Zaino is a perfect fit. For me, however, I demand something that stands out from the rest.
