Just to add to the wear around the flipper buttons, my Iron Man has the Candy Apple Powdercoated Armour Trim and it must be noted that the paint has chipped off (about size of a 5 cent piece but elongated a little) on the left side about 4-5 cms from the button towards the lockdown bar = lots of guys who are married (guessing). I checked the play count and 4200 paid games have been played.

So those people getting a AC/DC - LE or Premium just be aware, though not sure on the solution but you may start to see wear on the left side after a while. Maybe some vinyl start button protectors from pinball pal ????
