FTO AUSTRALIA

Hey so I've got a silver FTO and some dick keyed my car right through the paint. Looks like it got into the chasis paint as it's black with a duller shade of silver surrounding it. Don't think touch up paint will do the trick because it's a pretty large area on the bumper. Any ideas on what I should do?

Take it to a panel beater/spray painter and get a quote, ask what they intend on doing, make a decision after that.
