I have similar clear coat mounding at some of the posts on my iron maiden. Not ideal, but no cause to run for the hills IMO. It's a pretty minor thing which no normal person notices. The only people who would even look close enough to inspect for such defects are Pinside lurkers. Everyone else is too busy playing the pin and having a great time.
This is simply another manufacturing defect, like the peeling head decals, which will get sorted out eventually. In the meantime I will contine to fully enjoy all the new titles without freaking out.
P.s. if your pin has some clear coat mounding at the post don't go poking and prodding at it. That can make it chip. The ball can't touch it.
