It looks like it was done by an artist.
My wife and I used Haws Paint & Body Repair to repair, straighten, and color the bumper on her car. I used to build show cars and I have extensive experience with quality auto work, and the work that they did on my wife's car is as good as it gets. The line of demarcation is not at all visible. It looks like it was done by an artist. The price was also very good. On top of that, when we got the car back, the whole car had been cleaned and vacuumed.
