Quoted from PinMonk:
The only issues I know about with CGC is clear cracking and peeling on early run MMr playfields. Some were pretty nasty. But I haven't seen any issues since.
The point is there ARE manufacturers out there doing playfields so the clear can't be dented with a fingernail months after it's made and whole sections of the PF art doesn't come off from the PF wood clean. Reward them with more work and moola, and punish the bad actors (aka Mirco) who don't know or don't care how to fix the issues.
That was a known 50 years ago. Never seen this on an old Gottlieb EM
The question and what seems to remain unknown at this point that would help me better understand is this.
Did the same person make all playfields with this issue or are they made by different people exhibiting the same issue?
If it is the same person on all that is the root of the problem and it comes down to product lines or process. That could be addressed and fixed.
If it is different people then it gets deeper.
If different do they all use the same products or at least one or two of the same products in the process?
If not do they all start assembling too soon these days?
This type of info could really help find solutions moving forward but there is almost no interaction with the people that have those answers only those with the problems and aftermath leaving us guessing and many buyers suffering.
