Just got my MB playfield back from being clearcoated, which, after the process showed two spots where clearcoat hadn't taken properly. Having taken a closer look, they appeared to be holes in my playfield and sure enough, a bit of research showed that these two holes were in fact dimples. I dug out a few photos on line to show what I mean.
What on earth were these dimples meant for?
Just curious.....
