I used stainless steel paint as a primer, then a very dusty thin coat of cast blast to tone it down, then a very fine misting of satin black to further darken it. May not be correct, but it looks good and should last. other than the primer coat, the others are sprayed far away so the paint gets a rough texture and is not smooth. I did this to the hood latch too. Sorry, I do not have a pic loaded online showing this.
