Real Easy:
1) Go to Wally World and buy the 24 inch door edge protector. The one in the picture is slightly rounder while wally's is a tad flatter, barely perceptible though. It was bought at Advance Auto. The cost will be approximately $2.99 before tax. Yes, a really cheap easy mod that looks more expensive when done.
2) Instead of applying to the doors edge, same process obviously when you apply to the exposed window edge on the cargo hatch. Trim to fit. Actually after you cut to size on the driver's side, your left over should be the exact fit for the passenger's side. Just make sure you like the angle of your cut. I stopped where the glass edge ends.
PS- when the cargo hatch is in the closed position, it really matches the window trim especially if you look at both the finish product and the small rear windows on the side of the Rogue. The continuity is absolutely great (if not perfect) and looks OEM with the original Rogue window trim!
I guess for Nissan to save money they did not add black trim around the rear cargo window which is unfortunate as I always have to wipe dust from the bottom area of the window when cleaning the car.
