Quoted from sd_tom:Think it would be covered in scratches all the time though.. minor things you can't see on a normal play field might be highly visible, and acrylic is pretty easily scratched? Wax may do a pretty good job though of filling in fine cracks in this context..
either way, he's in uncharted territory.. sounds like time to work on some sample pieces before heading back to full playfield trial/error ?
Future floor wax (or whatever it's called these days). Used to use it to make model airplane canopies shine, since it would fill in the scratches.
Just kidding though. I have no idea if this is feasible.
