Carnauba content has nothing to do with a wax's shine. It adds to its durability. Carnauba is a hard dull wax. What adds to a natural wax's shine, is its oil content.
Manufacturers like Zymol, Swissvax, Dodo, Chemical Guys (They make Wet Obsession, e-zyme etc) use Carnauba content as a marketing term. As a "wax" that contains 70% carnauba would be a brick and impossible to use. Those high content figures are actually the % of carnauba in weight vs the other waxes found within the total compond as nearly NO wax product just contains carnauba as its primary wax content. Most contain candellila, paraffin, beeswax etc. Along with their other various ingredients such as oils, solvents, silicones etc.
Here's a little break down of some more popular waxes and why they are what they are:
Pinnacle Souveran: Very high oil content, goes on like butter, and comes off easy. Why? Low overall wax content, high solvent content, with a majority of oil content. This wax will look wet, but not last very long.
Wet Obsession: Medium oil content, goes on easy, off easy, as it has an extemely high solvent content. Tends to give a wet, but not deep look. Why? Again low content on wax, carnauba being the majority, but this wax is not natural, it uses silicones as a booster. Which gives it more of a shimmering look, that sealants give off.
Zymol Concours: Higher than normal wax content, typically in the high 30% (typically the true threshold of wax content vs total weight. Carnauba is near 50-60% of the overall wax content. Natural essentials oils, and natural solvent base. No slicones. Wax will last a good while, and give a natural wet/deep look. What do you expect for over $200? This is more of a 65/35 wax. 65% liquid, 35% actual wax. One of the higher waxes out there.
Swissvax Concorso: Again similar to Zymol, with the exception of it being less in the oils, more in the solvents, slightly more carnauba vs other waxes.
Hope this gives you guys a little bit of education on wax marketing buzz, as there is no such thing as the best wax. Only, the best wax for what youre trying to accomplish/budget.
Now, if you just want to win a show for best finish etc, just polish down your clear coat to remove all blemishes and jewel the paint with a non abbrasive lake country pad, like a red or gold jeweling pad. Although black and blue finishing pads can work just as well.
Don't even bother to wax it once the finish is done, just apply a show glaze (non abrassive), example would be like Meguiar's showcar glaze, or Chemical Guys EZ Creme Glaze etc, Adam's Spray Glaze (I'm not endorsing any of these products, just giving examples). These products are actually used to go on before waxes to "fill" and give an amazingly wet/deep look, but do not protect at all. They add dimension to the wax. But since we're trying to win a show, don't even bother to wax, you won't have any protection, but damn the car will look good for a few hours before the glaze evaporates off, since there is not a top coat to lock it in, lol.
