There is a company called "Plastic Surgery" that will repair anything plastic on a car, bumpers, arches, dash, centre consoles etc.
I tried a search for contact details and I got lost in all the breast implants and liposuction sites. I tried Plastic Bumpers and it got worse...found some of the weirdest fetish sites ever, so you will have to do your own research, I'm off for a lie down and a cold drink !! :dead:
