if its duct tape, ive heard that it flakes off, which is ok beacause then you get a battled look. if it's packing tape or anything like that, it will flake off really easily. (i've tried it) if its electricle tape, it will never dry, it will just stay sticky, which isn't good because if you touch it, it will make a print of you finger prints, or it will stain other things.
