As long as I've owned this machine, it's had an unsightly mylar edge near the shuttle ramp (when I first got it, I thought it was a crack in the PF. The mylar has pealed back just enough for some dirt to get under there. It's been an entirely cosmetic issue until yesterday when I noticed it was starting to guide the ball. From what I've read, removing mylar usually causes more problems than it solves and I'm not interested in a full restoration or replacing the whole PF. What's the easiest way to stop this from effecting ball play and maybe make it look nicer? Should I just try to trim the offending edge away with a knife? And if I do, what is the chance I'll lose some paint and graphics?
