When I had my ACE, my wife went to a fabric store and found a great product. It was a black semi-see through and one side had small very reflective (almost like mirrors) pieces glued to it. We ordered more window rollers from Amazon, they were easy to find. With a little sewing they went up very easy. We kept the original shades up also. With the new shades we could see out be folks could not see in plus the high reflective stuff made it cooler in the ACE.
