I was reading about both of them (Cquartz and Opticoat), and the opticoat seems to be a much more permanent solution. I'm not saying that cq. isn't durable, but on autogeek, it says that it lasts about 2 years. As opposed to opticoat which claims to last the lifetime of the vehicle.
Sheeeiit...I'll buy and use both! ...seriously. But which one should I apply first??
