Quoted from PinMonk:People go crazy and stick aftermarket, die-cut giant plastic mylar sheets over their playfields to "protect" them, and it usually is a bad idea, especially once playfields were clearcoated. He helped his buddy come to his senses and remove it from his playfield, restoring the way it was intended to play.
Couldn't agree more, playfield protectors are for people who put plastic sheets over their furniture. They play, and look like crap, and collect dirt under the edges, that can actually wear those areas more than no protector at all.
WASTE OF MONEY.
