Respray then by the sound of it i'm afraid!
I reakon it looks like a bodyshop job.
I wouldn't use chipsaway, i had them come out to my girlfriends car and the touched it up with a brush, i could have done a better job with a Halfords touch up pen.
get a PC on it and see what you can do with it. if it stays then itll need respraying.
did you make him pay for it ? or did you kill him ?
