It's the UV coating that breaks down over time causing it to haze over. Those that use wax to protect this coating can prolong the life of the UV coating. Direct exposure to the sun can accelerate this breakdown of the UV coating as well so parking your car .
Once the haze starts, one can apply various versions of headlight polishes/restorers, but each time one clears up the haze they are merely removing a thin layer of the polycarbonate, but since there is no UV coating, haze usually coming back causing one to repeat the process.
Currently, there is no cure for this problem.
