Duct tape helps fix leaking hoses, patches seat cracks, tapes doors shut until you can fix them, keeps your hanging bumper or underbody tray at the right height, fixes dangling side mirrors, and much more. If they can fix the space shuttle with duct tape, you can fix almost anything in your track car with it.
Duct tape also has pretty broad use at home and all around...
Our best advise is, get the jumbo pack and save big. You will find good use for all of it.
