Go with some sort of thick tape, and cut it in a zigzag pattern as per here. I'm guessing that a material store will have these sorts of scissors. As to where to find 1mm thick tape, not sure exactly.

I suspect that a lot of hatchbacks where the hatch is roughly 30 degrees or so might conceivably have good airflow with the addition of such turbulator tape. However, I have to wonder why the front windshield wipers aren't tripping the boundary layer. Or maybe the energy they add is too diffuse by the time the air gets to the rear of the car. Or the top of the windshield for that matter.
