I know its not an S3 R33 but when i got mine it was painted white, took it off and went to advanced sandblasting at brookvale, $70 later it was back to new, on the way home i stopped at bunnings and got a can of black spraypaint - check the results below
The guys at andvanced sandblasting werent too happy to be doing a car part so i was just REALLY polite and didnt push them for time - then they were happy to do it
