I have the 3M 8mil on my spats and it has a slight orange peel texture to it. It is very translucent, but not optically clear. You can definitely see it on my black car from 10 ft.
But it has totally saved my paint job where applied. The front of the car and front & back of all fenders are nicked up from crappy roads and track time. When I get the paint touched up, I'm going to add much more of this film.
3M makes a Scotchgard film that's only 6mil, don't know anything about it.

Llumar's film is optically clear, but not sure of the thickness.

Sal, your car is white, so you could get away with the 8mil and you shouldn't see it at all.
