Iron Man Helmet detailing

Hey, I bought a cast of an Iron Man Helmet which I believe was made by monkeeman.
I am just about to start finishing and painting this helmet (when funds allow for paint and filler)
I have searched for pictures of the helmet but haven't found any from good angles showing details, so I was wondering if anyone here had any good pictures of helmet details from screen shots.
I am planning to use this as a display piece, I'm not planning on lighting the eyes, just want to make sure I get all the detailing right.
Mainly I need to know if the grooves running around the sides and back of the helmet are black, as some finished versions seem to appear this way. Also I was wondering about the eyes, if the sideshow bust is a good example I will follow this for eye detailing.
Any help would be much appreciated and thanks in advance.

Most of the images i've seen show the lines as simply the same red as the main helmet. Some people here have added a black wash on the grooves as more of a weathering effect than anything else. Depends on which look your after. Freshly painted by Jarvis or weathered/used, or battle damaged.

Thanks very much.
I'll try and get started on finishing my helmet soon.
I'll just have to wait and see whether or not I should add weathering or damage to my helmet when i get to the point of painting it.
I've seen a couple of really nice examples of damaged helmets on here, I'm just not sure on the process, if it's air brushing or just sanding off layers of paint on certain areas.
Anyway, cheers for the info. Any help/advice is much appreciated
