Quoted from NM:
Never put Pincabs on decals--they can cause impression marks immediately and eventually wrinkling.
Install the new Stern stand-offs from PBL instead: ingenious design, because they never come in contact with the cabinet.
Pincabs work nicely on original silk-screened cabinets, not replacement decals. Pincabs also serve to cover existing wear--but on games that were screened on white vinyl sheets applied first to the cabinet, using felt under the Pincab is cheap insurance.
Here's a photo I saved of what happened to someone who unfortunately wasn't aware of this--and the resulting damage from being applied just one time on fresh decals.
Excuse the stupid question, but how exactly do the ones from the link posted not come into contact with the cabinet/art?
To me it looks like it is just a metal plate that installs between the cabinet and legs, in which case would it not touch the cabinet - or am I missing something here?
