Well true both would help with less friction from metal to metal. Though a grease like substance will gunk up over time, especially in the lug nuts and will give inconsistent tension results especially when finger tightening the tension rods. 3 n 1 only creates a residue that's easily cleaned with a can of brake cleaner. That goes for the rods and lug nuts. Sure they both help with friction but with continued use one will gunk up more than the other over time, especially in the lug nuts.
