I searched existing threads but couldn't find any clear recommendations. I'm in the middle of replacing valve covers on my 05 G35 and the wiring harness is super brittle. Looks like its just electrical tape wrapped around it. Does anyone have any good recommendations on a better wrap for this vs crappy electrical tape?

If electrical tape is the way to go, any recommendations on brand? I'd like it to be red to match the body color and the valve covers I just painted.
