What appeared to be a large brick smashed and shattered Dean Marcic’s windshield as he was traveling with his wife across the San Francisco-Oakland Bay Bridge toward the East Bay a couple weekends ago. Miraculously, the ultraviolet, aftermarket $400 protective layer Marcic had put on his window prevented the large rock or hunk of concrete from penetrating through. It may have ultimately saved his life.
