I went to look at a newer Spike system game. It was a routed game so I expected it to have coil dust over the bottom of the Playfield. But the weird thing is it has what seems to be coil dust over the entire machine. All over the inside of the cab everywhere, all over the back Box, in electronics even the translight is covered in this black dust. It looks like someone took a garbage bag of black coil dust and just dumped it all over the machine and its components. Does anybody have any experience on what this could be?
