Well, I caved. Once I got my tax refund I couldn't help it and I got one of the airsoft shields. I managed to get it for about the same they went for when they first came out so I don't feel too bad.
Oddly, my box wasn't cut up like most and the website on the back of the shield was in tact, not sure if this is just a supplier thing or not but the site doesn't work either way.
Sorry about the glare in that second one. I could only get the 'tan' though the color was definitely a greenish color to me, but either way it was not what I wanted and I know these can be tough to paint well so I wanted to give myself every chance for success, which meant stripping that paint off and without a sander it was definitely not easy. But, 4 hours and lots of dust later I've got this:
I didn't really takk the paper to the back but I did sand down a few imperfections and the company information down flat. I havent done anything about the indent from the star or the dip in the plastic in the middle but I have some styrene hanging around so I might put some of that in there like someone else here did. At this point I don't think I'm going to do the screen-accurate brakets though, my costume isn't really anything that's been in the movies and the comics have a different strap system depending on who's drawing it, so I'll probably just figure out something on my own.
I've got a friend coming over with a dremel later tonight so hopefully I can get the engraving in the star and start painting soon. I've ordered the dupicolor anodized colors and I already have a primer and 'brushed aluminum' from them so I'm hoping it'll all work out. I've also got some rub 'n buff in silver that I might try out for the silver ring and star to get a little more shine out of it, I'll probably test it first though.
