A couple of things that I have done that I have found to be improvements are:
Using tubular webbing material for the loops instead of nylon webbing. It's softer on the car's finish. Like this - Example of tubular webbing
And, to protect from rubbing, is sliding pieces of car door edge protectors onto the hood and tailgate. Not this one but like it - Car door edge protectors
