Carnauba Wax comes from the fronds of a variety of Palm tree that only grows in Brazil. The wax is very durable and one reference said it is harder than concrete. It protects the palm leaves from the constant intense rays of the sun in the tropics. So it is ideal for protecting your car's paint. There are other products that last longer, but nothing matches the rich and deep warm  gloss that can be achieved using Carnuba wax. It should be applied, ideally, to paint that is not only washed, but depending on the condition of the paint, polished and or clayed to assure it will cover paint that is not  opaque due to oxidation. Only then can it achieve it's complete potential. Apply it with a sponge applicator in a circular motion using it sparingly to one section at a time, allow it to dry to a light haze and remove it with a quality microfiber cloth. Then buff it by hand or orbital buffer. Carnauba wax varies in price by manufacturer and can be very expensive. Previously, my favorite product for the most bang for the buck is called P21s Concours Carnuba Wax. The results if used patiently are spectacular and it costs about five dollars an ounce. My ultimate choice is Pinnacle Sovereign Paste Carnuba, but it is a staggering twelve dollars an ounce or almost $100 for an 8 oz. tin.  This Griot's product costs about $3 an ounce which makes it a screaming bargain by comparison. I found it easy to apply and the gloss is very good. My only question is how long the application lasts. No wax lasts forever and if the results last 5 or 6 months as the two products I mentioned will, that is outstanding. I read some comments of people who said this product did not have that longevity, though I will need to update this later to see what results I observe. Considering how much work and how time consuming it is to detail your car, I think paying double or more for a product that lasts longer is actually cost effective. My results so far are encouraging with this product; easy to use, good shine achieved, very reasonable price comparatively. If it has longevity, this will prove to be a real bargain.
