Just to add my two cents worth re a paintless dent removal guy I reckon is amazing!

I know your post is re a scrtach, and this guy doesnt do scratches, but if anyone ever has a dent of any sort later, this guy is definately worth calling in Sydney:

DENTS R US (Dragan)
0419 232 754

He has done many jobs for me, and even when he is not 100% happy, I reckon the results are perfect. He is so fussy, and very well priced.
