Thanks for checking in. Let me start by clarifying a few things for you. First of all, Grit Guard is a name brand, not a type of product. Yes, carnauba is very good wax, and yes there are many different types and prices. You can easily go from $15 up to over $1000 for a jar of carnauba wax. And to say that it only needs to be applied twice per year is incorrect. Most paste waxes only last 4-6 weeks, whereas sealants last 4-6 months. And both of these products only protect from the elements…they do not protect from swirls.
