Please upload at least 2 photos.
1) First Picture needs to be Up close, where you can see the dent clearly. For small dings, Try to get the dent in a light reflection if possible.
2)Second picture needs to be a picture of the entire panel. Take a step back and take a picture of the whole (door, fender, hood, trunk, etc.). So we can see where the dent is in relation to the panel.
That's It!! If you feel it requires more pictures to properly show the damaged area, then feel free to upload as many pictures as you deem necessary. The more the better, so we can properly quote and schedule the time needed to complete repairs.
