Here are those photos and why I am leaning to removing the mylar. I feel if I don't the damage will accelerate and I would rather attempt to do a mylar removal and a restore followed by a automotive strong clear coat. Because of the bubbling and peeling and some cuts and scraps I don't think a decent touchup could be achieved as I think it will always be the weak point of the playfield in relation to future wear.
I do not know the history of this playfield but it suffered a little bit of abuse and I am very keen to restore and give this pinball some life and be played again as the theme means alot to me.
I am a novice but with some desire bring it back to life.
