nissan 732 black (not the typical kh3 black) is pretty nifty
i think it has some gold flake in it… looks really good
its not only the paint that will affect ur paint job but everything shows up on a black paint job. Imperfections in the body lines so u need to block it. It makes sure everythings a straight line. Any scratches or imperfections in body panels need to be fixed. The prep work is the most important step. ESPECIALLY black. Its a hard colour to paint aswell.
As for which black to use sorry i dont know, just thought id put my 2 cents in on the paint work. U probably allready know this anyway
Tremclad Gloss Black 
Best 5.29+tax I ever spent.
black shows poor bodywork easily. the one way to mask that is a paint job with a lot of metallic or pearl flake.
RSX black is nice though. I don’t like the Nissan blacks, they look a little too flat.
My body shop suggested going with a Toyota color, Black cherry metallic. I’ve seen a paint chip and I think that it looked real good.
yeah toyota has some of the best oem colours available!
