In late 2002 as part of a "thank you" for some work done on their house, a relative of mine got my son and I our own NAR Gunblasters. My son quickly built his but I waited until I had more free time. I knew as soon as I saw the gold spikes on his Gunblaster that mine would be some other color.
This was trivial as far as spray paint jobs go. I simply spray painted the gold parts a light gray. I didn't even have to mask anything. Everything else is right out of the box. I like the gray color much better than the gold.
