Black Leather Repair Tape

Fancy duct tape

GREAT

Did not fare well in my garaged car.

I have a leather cat seat that had started to split, so I cleaned the area with alcohol and applied some of the tape. After a month, it started leaving a residue around the edges that spread to nearby parts of the seat. I was able to remove it with no effort, because the adhesive had failed to hold—leaving additional residue that had to be removed.
