I painted my heat shield because the gold/green color did not match any of the damn engine. We own a body shop so I matched the color perfectly and cleared it. Didn't get a chance to add the second part to it yet though, but honestly I don't know if I should. I am planning on also, to the left side of the heat shield (facing outwards, towards the engine) airbrush a black 350Z logo. Our airbrush guy is very talented and I am sure he will do a great job. But I don't know whether to do that or leave it gray metalic. Any input would be appreciated, thanx!
