I agree that percentage of carnuba alone shouldn't be deciding factor of wax quality; however, Titanium, Destiny, Ital, Vintage, Atlantique, Royal are all Zymol estate waxes. The percentage of carnuba is almost directly proportionate to price with Royale topping at 71% white carnuba and the highest price tag $7,000+. I am not sure is there is an appreciable difference amongst the estate glazes. I will admit that Vintage can seem a bargain becuase it is refillable where Destiny will by $500+ per tub. When I ordered my Zymol products today, I was told that Zymol is going to have price increase. HD Cleanse was going from $39 to $42. I do not know how estate waxes are going to be effected.
