This is another print and paint of mine, it is the Star Trek Renegades Combadge. Star Trek Renegades to all who don't know is an amazing Star Trek Internet series with a TV Movie coming out in 2014. It is an amazing series and being from the makers of Star Trek of Gods and Men, it has to be good. Many well known Star Trek actors and actresses will appear to reprise their roles with many new exciting additions.
Their website: http://startrekrenegades.com/home/ Is amazing and tells you all about what's upcoming.
Please make sure to check out their website and check them out on Kickstarter as well.
Another website to check out would be: http://www.startrekphase2.com/ Which is a revival of The Original Series in a second 5 year mission. They too have a Kickstarter page which is worth checking out.
To Paint, a layer of Gold (matte or gloss) and then paint the top of the badge silver as in photos. You may wish to scale it up as it is a bit small as I have found with previous models.
