Don't even think of duct tape. Really, it is nasty stuff. Whiteymorange's suggestion of bookbinder's tape is better, a good acrylic black paint or E6000 would be good. I don't know about liquid electrician's tape, but it sounds sort of like E6000. That would probably be good, too. I wouldn't use 3m photo tape for anything permanent that will need to flex repeatedly. It lasts a long time if it's just stuck down, but I doubt it would hold up well if it was bent time after time, as it would be on a bellows.
