I never would do what you suggest but I always had the network room door codes. Scotch tape and a thin plastic needle to rub it down to blend the colors on the copper part of the cable, then into the patch panel.

I once playfully threatened a helpdesk senior manager: if you dont tell your team to shut to coffee pot off in the evenings I'm gunna start putting your LTO tapes into the carafe whenever Im forced to be here at 2AM cleaning a coffee pot so I don't take a box cutter to the entire patch panel.
