Ah, springtime.  Time to restore the steed after a long winter of rain, wind and grime.  Out where I live, it is also time for green sticky pollen to start blowing around and collecting on my beautiful old M3 - and thus time to get a smooth layer of wax on the car to protect it and make it easier to keep clean.To take full advantage of a high quality, high carnauba content wax like this, start with a good wash and hand dry.  Then you may want to give the car a rubdown with paint cleaning clay, to remove sap, bugs and any other contaminants that remain.  Whether you skip the clay step or not, you absolutely should use a lightly abrasive polish - 3M Imperial Hand Glaze is my choice.  And then, once all that prep work is done, a good carnauba "paste" wax for post-polish protection.I usually use P21S carnauba wax, but along comes this Griot's Garage "Premium Carnauba Paste Wax" from Amazon Vine.  So, is it up to snuff?Yes, absolutely.  To be honest, it seems to me a lot like rebranded P21S.  To call it a "paste" is a bit of a stretch.  Like most waxes with high carnauba content, it is more like a solid block.  You can use it with one of those machine polishers, or so they say.  Me, I apply by hand using a foam applicator pad.  You rub and rub the surface of the "paste" and get just a bit of the wax on the pad.  The friction and heat from your hand begins to melt the wax down, and it applies in a light, smooth coat.  Remember this, especially if you are applying and buffing by hand -- don't wait around for it to dry completely, or it will be a bear to buff off.  Thus, apply it one small section at a time, give it a minute or two at most to begin to "set," then buff, and move on to the next section. Unlike those 'one-step' polish/waxes, this wax won't leave a chalky mess behind and it will not clog your buffing cloth, whether you use microfiber or soft cotton.Like most natural waxes, it isn't going to last and last, like some of those hard shell, plastic polymer sealer waxes.  But it is going to make your car gleam, assuming you have properly prepared the paint before you apply the wax.  Water beads up and runs right off the wax surface.Some folks here have suggested comparing this wax with products like Turtle Wax "ICE."  That's apples and oranges. ICE is a silicone wax. It's inexpensive. But all is not sweetness and light. Granted, cheap silicone waxes can create a 'hard shell' coat on your paint. Alas, they also will eventually make the paint on many fine cars - esp. German marques like BMW, MB and Porsche - become cloudy and will be a bear to remove. Don't even think of it if you care about your car.Three times a year, that's my usual drill with comparable carnauba paste waxes, and I expect that will be about right with this Griot's Garage wax as well. However, having just received and applied this wax, I'll have to report later on its staying power.  But for now, it is easy to use, looks great, and seems to be a dead ringer for my accustomed P21S.  I'd call it a toss-up between the Griot's Garage carnauba and P21S carnauba, and will use either one with pleasure. This is good stuff.
