Well, This isnt exactly what you're looking for, But perfectly does the job just as well, if not, twenty times better.
There are several mods out there that Remove the scratches on the canopy when you have reflections enbaled, so that you could still see the typical reflections and such, but not the scratches which may give you a big FPS hit, or may be graphically renderred incorrectly because of your card/drivers.
