This is a set of two mylar protectors for Foo Fighters.
One is for the area in front of the target bank that can chip near the edges. The main image is with the paper backing on so the protection area is visible. The second image is with the mylar installed. Third image is an example of chip damage on a stock playfield.
The other protector is for the ball launch. The factory mylar is too short to protect the playfield because the ball often lands AFTER the end of the factory mylar. This piece is meant to butt up against the factory mylar, continuing the protection so it's over the area where the ball lands. First picture of this area is the protector with the white backing so it's clear what it's protecting. The second picture of this area is with the mylar installed. The third is an example of the damage this mylar is intended to help prevent. Finally there's a animated GIF of a ball launch showing how the ball lands just past the end of the factory mylar (noted with the yellow line).
