I have a '25 Stealth with about 25,000 miles. I can comment on wear, but not fading from sun exposure (garage-kept).
One very limited analysis later, I've identified 5 unique Stealth elements on the front of the Air:

Part #1: This is an extremely thin layer that coats (what seems to be) a truly-Platinum component. I did not opt for a PPF, and there are a
lot of tiny chips in that film at this point. The LUCID script itself is still in good shape, but not perfect.
Part #2: This consists of the lateral light bar. The only damage I've seen here is from the frunk lid contacting the outermost point while opening, leading to a small piece flaking off. It holds up fine, otherwise.
Part #3: More of a matte finish, and still looks great. There's a strip that runs just above the headlights and LIDAR which is very similar.
Part #4: No issues with the DRL/turn signal assembly.
Part #5: Specifically the section that runs beneath the intake vents. Easily the most-damaged part, presumably because its lower height leads to tumbling rock impacts on the interstate. That said, I haven't seen any "peeling"; just dozens of small, silver dots. They're hard to spot unless you're inspecting the car.
My wheels are the 20" Aero Lite. I removed the aero covers as soon as I received the stealth lug caps and center caps; you can request these from your nearest SC. I've heard that the aero covers can cause scratches by the way of the clips that attach them to the wheel. In other words, probably best to remove them immediately or keep them permanently. I preferred to see the rotors & calipers at the cost of range. I get about 400 miles of the 480 advertised.
My mirror caps pick up a ton of bug impacts, but no damage. My roof frame (A-pillar to C-pillar) looks flawless. No issues with the bow. No issues with any rear or side skirt elements.
I don't regret going with Stealth at all. I do regret listening to my local tint shop's suggestion to avoid PPF (they warned me of yellowing and dirt collection on the edges). At the very least, I'd consider covering Parts 1, 2, and 5 if I had another opportunity.
