had the same problem with my car (Red) done by the dealer, refused to pay for the job and after 6 months of fighting with the body and paint manager I asked that the owner of the dealership to look at my car, he did and asked me who did the work? He told me to return the car and they blended in the paint with both rear quarter panels. You cannot stop a painted part in a straight line it will show you need to blend the paint with the existing paint around the damaged area. Insurance company s always pay the minimum and will not pay for the extra cost of the blending,,,, you will have to insist that they do the work correctly.

thats what they did on mine and the car came out perfect.
