When i bought my Z it had a cheapo black tint on the rear windscreen. This was the type where it's like a film of plastic with some kind of tinting dye underneath. It had bubbled and it was impossible to see anyting out of that window.
I've managed to remove the film without taking any of the heater elements with it, but the screen is still covered with this kind of powdery black residue that seems stuck fast.
On someone's advice, i tried white spirit and a plastic kitchen scouring pad. This does work, but it takes forever, and as you can imagine it's an awkward angle to be scrubbing. In about half an hour i had only managed to clear about a 3 inch square off the glass.
Does anyone have any suggestions? Is there are better solvent to use than white spirit? Or could i use an electric sander with a scourer instead of sandpaper?
