I have seen this paint scheme on 3's before, only the version I picture for my paint would start silver and fade to full black.
There are a couple of threads around the various boards on the LTW flag decal.
Apparently they are available on eBay in colors.
I need a respray up front, and I think I would like to have this airbrushed into the paint, but faded so you can only see it in certain light.
