Front bumper scratch

[Saffer]

Hi guys, this may be in the wrong part of the forum but a quick question on bumper repair. I have only had my car a short time but already infuriatingly it's managed some damage on the front bumper at the bottom under the grill. The staff multi story carpark where I work is having major repairs done and so has a lot of tight squeezes and corners to get your car into to park/move around. Trying to get the car as far out of the line of fire from the workmen as possible I managed to just nudge the bottom lip of the front bumper against the concrete wall enough to scratch it. It's not particularly bad but enough that it will need touch up paint and maybe a sand down before hand. Should I do it or let someone else do it?
