1985 called, they want their duct tape mentality back. Electrical tape is garbage for chafed wires because it doesn't hold up to heat or oil, it peels off after a few months, and it leaves sticky residue all over the harness. I've seen guys use it on a sensor wire in a desert truck, and it melted into a goopy mess by noon. Real fix is split loom tubing or heat shrink if you want something that actually lasts. Tape is just a bandaid that fails when you need it most.
