Only done a couple, but taking the screws out is a HUGE time saver...with all the caveats mentioned. While they are out, you can spray them with a neutral colour so the don't affect the graphic as much as a shiny dot! Re-install with a drill with the torque clutch set way down, and just gently do the final turn by hand. It appears that most of the cladding is also glued to the frame structure, so it didn't pop off when screws were temporarily removed...but I wouldn't drive it down the freeway like that!

If your design is going across white AND black, I'll bet you can accommodate the silver checker element, just as you would a window job across two panes.
