I was looking at some paint coatings such as Carpro Cquartz, Optimum Opti coating, and Gtechniz C1 and Hybrid Coating. Is it really worth the money because I currently use a synthetic wax and then a carnauba wax when washing/ detailing my car. They come in rather small bottles and cost around the same for what my waxes I use but the waxes I purchase can last me 5-6 cars vs 1-2 for the paint coatings I listed. My area I live in the winter is a little harsh so I was looking at them to help protect the car paint.
