From a spray can, Rustoleum textured black is very close. It has a very fine texture like original.

From a gun I've heard of using application techniques to get that fine texture finish. Maybe someone with experiance at that will chime in.

I've seen stuff people have shot from a gun look not right. Whereas its pretty hard to screw up the Rustoleum textured. The Rustoleum texture is above average for spray can durable, but real paint from a gun should be tougher.
