It can be the little things sometimes. Like not marking up the panels of your gear and not leaving a sticky residue by not trying to mark up the panels of your gear. Solution? Drafting Tape. If there's something that leaves behind less adhesive, let us all know, but I haven't found fault here. Great for consoles, rack gear, and marking out notes on a piano/keyboard for a non-musician.
(The general rule for any adhesive tape seems to be the longer you leave it on, the more likely it is that the tape becomes one with the surface. If that comes up, maybe I'll need to do a later installment on WD-40.)
