Quoted from CaptainNeo:no. can happen anytime. Sometimes as little as a week. Sometimes years, sometimes never. I've playfields from everyone, manufacturers, and restorers have ghosting on the way to the destination.
happens, from stern, Bally, Williams, Zaccaria, Taito, Inder, Data east, Sega, Gottlieb. And seen it happen from every restorer. No matter how you prep a playfield. If you get expanding and contracting at 2 different rates, it will create a fault line, but can also pop it up along that fault. there isn't any control over there. Better prep will reduce it, but will not make it impossible to happen.
Total horseshit. You're defending a possibility, this has become the new norm and it is not acceptable. Your statement lets them off the hook. Again not acceptable.
