GADZOOKS! that's not good, all for one scratch. Thanks anyway.good luck with that.
It's something wired like deep blue black chrome and I'm not sure it can be replicated.
I remember seeing the suggestion that the paint was for sale on ebay a while back and was listed under a slightly different name which was preceeded by the word NISMO. It wasn't confirmed it was the actual paint but it sounded and looked like a good bet.
Difficult parameters to search under, sorry, but it's the best clue I'd ever seen.
Most people end up abandoning the colour and going for something close on all four wheels.
