That sucks. Contact Chas and hopefully Stern will send you a new lower playfield. I noticed a track forming on my lower playfield from the ball being shot out in the same line repeatedly, so I added some mylar there, but that area was directly over the graphics of the blonde woman. The spot you're apparently missing paint from to the lower left of the right playfield post is an odd spot for paint to just pop off. I wonder if there was some contaminant on the wood when that area was painted that prevented the paint from adhering properly?
