Its all in Plasti-Dip which is a rubber coating that comes in a spray can. Basically all you have to do is mask off the area around your target and leave a small gap between the mask. You can then peel the excess off the body and it will follow the seam. Pretty cool stuff, But it leaves a small texture, which I don't mind because it closely matches the other black plastic accents. There are so many Plasti-Dip tutorials on youtube, I decided not to do one. But I have yet to do the back accents and will make a tutorial if there's a request.
