The part usually comes primed, but you'll need a painter to colour match it to the car. Audi will do this, for a price.
But contact my man Alex at
http://www.europrice.us and he'll hook you up with a new one (cheaper than what Audi will charge), then it's up to you to find a local painter.. the guys at BWA Auto in Seven Hills might have a 'go-to guy' they use a lot, try calling Craig there and asking.
MEANWHILE... where on earth did you put the jack that you managed to 'screw the pooch'?
