Interesting point, aluminum is softer than steel. Since parts are at least twice as thick that should more than compensate. That made me think why not machine some pinballs themselves out of aluminum? Of course they wouldn't last as long as steel but with the reduced weight they would fly! They would probably be right between a ceramic powerball and a conventional steel pinball as far as speed goes. It would be a worthy experiment.

Cudos to SickNate for this amazing project! I wouldn't be surprised to see your new style pop bumper adopted commercially. Brilliant design.

"we will ride shiny and CHROME all the way to the gates of Valhalla!" Was a great line in the movie when they used silver spray paint to paint their mouths. So, a silver powder coat on the ramps might tie into that nicely. Another idea might be to get a printer to print wraps for the ramps simulating the reddish dirt roads in the wasteland maybe even with some of the vehicles printed on them. If the ramps tie into a chase mode in any way that might work. I'm a sucker for chrome but this is such a great theme the options are endless.
