Hey, sorry missed your comment! I'm hardly ever on 405th anymore so I miss that kind of stuff.
The visor in the older posts is krylon gold paint lightly dusted and then followed by krylon looking glass. I like the look a lot, but it lacks in visibility. The newer helmet (professional shoot with graffiti background) has a yellow tinted visor with airbrushed chrome behind it. Visibility is much much better, but does require some more equipment and practice to pull off. Hope that helps, post your progress when you do it!
