black gaffer’s tape is perfect for covering LEDs long term without any residue.

maybe i just bought cheap tape, but i've definitely found gaffers tape to leave a residue if left in place for a couple years. especially on electronics that are generating some heat.

The good stuff is like 20 or 30 bucks for a roll. I just pulled off a piece that was stuck to glass for 4 years and it came off residue free.

There’s some really crappy offbrand gaffer tape on Amazon these days. The “pro gaff“ brand which costs around $30 a roll is the good stuff I recommend. (Source: I run a theater and pay hundreds of dollars a year for gaff tape. I have tried a wide variety of brands and price points.)

I would be worried about that.. had some gaffer's tape in my car's interiors, left horrible residue after a year or so.
