Well ive got the same provlem on my srt, its so annoying! When you look really closely the hazing is made up of thousands of tiny surface cracks so i bought some headlamp haze remover. Gave it a try and it did make a little difference after 3 attempts but i think im going to go for one where you sand the top lay slightly then buff and polish it all up afterwards. But depending how bad your hazing is, i would defo give one of the diy polishing kits a go, it does help.
