That would be really hard to paint match due to the location and obviously 'cause pearl white is the devil to painters. If it were in a different location such as all the way in the corner near the splash guards then it would most likely be a lot easier and doable.
I was quoted $400 to fix a slightly smaller dent on my bumper right below the 370z emblem. $400 to respray the entire bumper or else it wouldn't look right and my car is red.
