i have pre-tinted lexan in my rear window, but i guess at 1:00 in the morning that was a little tough to see.
i will be using it in my quarters soon. i bought it from your average glass shop in town. i think the rear cut to size was around $20-$30. and i think they wanted $30 for both quarters. aircooled.net sells full kits i think, but don;t think they are tinted.
