you should. I knew a chick that use to do it and she'd use silver n it really made it pop like you wouldn't believe. There was so much to look at. It was unique like a cletic fractal sort of thing. Pretty awesome. But she was a constructive graffiti artist, only did it on big boards she bought herself for herself. Think she works in a youth centre now encouraging respectful graffiti, in other words only on public walls with permission or on boards.
