Not to beat a dead horse, but outside of being a certified wax chemist, one would have to categorically prove (with scientific evidence and not heresay) that any wax maker's claim that an ingredient configuration is in fact truth or tale. We have had a wealth of discussion about the validity of certain products and the various claims, and outside of documented proof of workable wax consistency percentages (to which this day I have yet to see any documented scientific study that notes the limitation of a certain percentage of carnauba that's useful in automotive wax), all of the discussions on certain detailing boards about the validity of certain products have amounted to more heresay than actual fact finding.
The bottom line is that manufacturers such as Zymol (there are a few others that charge a lot as well) continue to make and market their products without sanction. To more than a few experienced consumers, these products have shown themselves as being distinct from their competitors, thus their presence in the market continues to thrive.
The prices of some of those high end products are ridiculous (and I say this as being a consumer of one of those products); However I stop short of calling any product bogus, much in the same vein that I caution the word "best" to describe certain lsps. If your individual objective can be best met by any product, regardless of price, then that is the most important goal of using and enjoying any detailing product.
