I found a sratch on my car

and I need it fixed because scratches lead to rust and we all know thats the worst. I need some Granada Black (NH-503P-5) but I cant find it anywhere (even dupli-color doesnt sell that color). Im really not into going to the dealer and spending the "dealer fee" for it, and a shop's fees are damn near the same. If anyone's got some info or a hook-up on whre I can get some of this paint, that be sweet.
