I feel it is a engineering flaw since the composite of the material used is softer that the jk. I have had two other Wranglers that did not dents and damage like my Jl. They did have mudd tires on them. Purchased the Rubicon so I would not have to change out tires.
I have rock damage on my rear fenders and also paint is chipped. Front tires are throwing back the rocks. I feel it is a engineering flaw and should not look this way.
