Have they improved Reload? I used the same combo a few years ago and felt the Reload was very weak. To confirm, I cleaned up another car and only applied the Reload...it basically was washed off and gone in a couple weeks. I started using Griot's Ceramic Speed Shine as a topper over the CarPro CQuartz UK 3.0 instead. Much better results.
Nothing is going to last 10 years. I find many of the spray on, wipe off ceramic and graphene sprays to be quite durable and easy to use. Many, like the Griots 3 in 1 Ceramic Spray Wax, and NuFinish Graphene Spray will easily last 10 to 12 months. Pretty impressive for a spray on, wipe off product. They are super easy to touch up too, as I find the lower parts of the car will lose their hydrophobic properties first, from rain spray on the freeway (I live in the rainy Pacific NW).
My experience is opposite your's- put some of the adams graphene ($160 for a small bottle) on hood as an experiment and its still there after 2 years. Cant get it off if I wanted to, but it all depends on car use and environment
