All valid points. Its expensive, you shouldn't use brush car washes again, and needs periodic refresh.That is the part I don’t trust the shop. They claim PPF under ceramic coating is a lifetime. Anybody with common sense understand nothing last forever. So according to your experience even just for ceramic coating it is $1500 plus $125x20. The cost including tax and inflation over ten years is potentially over $5K already.
So the part of my argument that is subjective is that keeping our LC shining and splashing really worth this much money? When I drive my LC at 2040, would I care more how good it looks, or how well it runs on and off pavement?
I do, however, want to tint my window as it is more functional rather than aesthetic. Without it everything inside the cabin degraded at least several times faster given I live in southern state close to the desert.
Why i did it. I foam canon wash and it is great time saver for that. I dont want to wax my car again. Park outside often and gives me more hardwater spots, bird and sun protection.
My opinion after having it now for a month. Improved shine and depth like a wax does, keeps car cleaner longer, i can often just blow off dust or Easy spot clean a bird dropping. Power canon washing is easier and rims stay cleaner or r easier to wash.
To me would be worth doing it on a black car. Less so on a white car.
