Scott was exposed to drawing at a very young age, but his career as a dirty car artist began when his vehicle got blocked in at a parking lot.

On average he says he spends between an hour and a half and three hours on each drawing. Here, his take on Stephen Hawking and Albert Einstein. Be sure to check out Scott's official website for more.
