Is the DirectTV even 15" in diameter? It needs to be symmetrical, a 'body of revolution' if you will.
The first picture in #34 is "plain and boring", the 2nd one looks Blurred in Photoshop. If you get bigger disks you will have to deal with the wheel balancing weights (notch the disks or use stick-on weights) used for mag wheels.
One could jack up each wheel (or do 4 disks on one wheel) and spin it while holding sandpaper against the disk—just enough to hide those random marks. It'd look better when they're turning.
