I am warming to the idea of nudging, but only on my unrestored pins with cabinets that have not yet been restored. I was pissed when my BBB got leg wrinkles, but have a set of decals spare so not too worried.
On my MM & IJ when they were restored and before the metal protectors were about the restorer cut the plastic protectors so they were flush with the bottom of the cab on all corners and screwed them to the cabinet. Guess he was onto something!!
