So I have a 2018 Big Horn in the same color (granite black metallic). I have a couple of show cars and always have used the same product and the same procedure with terrific results although it can be a little labor intensive, especially the first time. So what I do is first wash the vehicle twice with blue Dawn dishwashing detergent. This takes all grease and wax off then I clay the vehicle to get imbedded imperfections and dirt off the finish. Then wash it again. Then I start the waxing process by using Zaino Brothers products. First, you put on Z1 which is a wax locker. You wipe it on and do not take it off. Next you use the proper wax, for a clear coat paint in your case. Put it on the entire vehicle and then take it off with a 100% American cotton towel. I always put three coats of this wax on over a few hours, not immediately one after the other. Finally I use a spray "wax enhancer" that really brings the metal flake out. Spray it on one section at a time and wipe it off before moving on. It is so slippery at that point that if you lightly toss a towel on it, the towel will keep right on sliding right off the vehicle. I use the lock once a year and the wax every 3 or 4 washes, but use the enhancer after each wash. Since I discovered this process back in 1999 I have used nothing else on any of my cars, trucks, and motorcycles. If nothing else, I suggest you go on their website and do some research. I am sure there are many good products out there, but this is the system I use so I can only speak for it.
