It's important to really look at your WOZ for wear every so often. Mine chipped around the Winkie so I repaired and covered with Gorilla tape - seems to be OK so far. (Aug 2014 build date). If you don't fix a small chip it will quickly become a bigger one. I've probably got about 400 plays now but the problem happened about 200 plays. No problems seen anywhere else.

Although I have played my WOZ several months now I'm still amazed to hear or see something not discovered before. I was just cleaning the glass and the tin man says "You want me to oil the flippers?"
Someone at JJP has a great sense of humor.

I had a small fingernail size piece break-off near the winkie. JJP suggested some touch up paint but that flaked off as well so I touched it up then applied an overlay. That seemed to do the trick. I also dialed down the pops just to be safe. I've had no more trouble so far.
