Welcome Jack!
@david1972 Ill second that, bought some after your comments post fence incident and it works well on scratches.
Id be surprised if they had to do the whole bumper tbh! I had my old Vectra with similar done and they just did the one end which looked fine. The dink looks like more than can be pulled, from the photo, so might need a bit more work.
If all else fails I just put a sticker over it
