My car is supposedly an onyx black, oem code 202. I'm about to paint 4 panels on the car. Jet black is so much easier to obtain around here, and i think it looks really good. Now, is the difference, if any, that significant? and what's the difference anyway? I'm only painting the 2 fenders and 2 lower quarter panels on a Lexus, and depending on money and results, i might paint the whole thing. Due to space, i can only paint a couple of panels at a time. Help is greatly appreciated.
