I have a G35 and the headlights haze every month. I polish out the hazing yet it keeps coming back. What products would prevent the hazing from returning? You would think a product with UV protection right? I've used Zaino (Z2 & Z5 Pro, with Z8 applied after almost every wash), OCW, Aquawax, and I'm sure a few others but the hazing always comes back (and it looks horrible on a nice black car). Any suggestions would be appreciated.
