The Stage 4 Photo shows a second colour of Antron Body Wool or any other material for that matter being applied. In my sample I have used Chartreuse or Fluorescent Green. The finished results of applying the second colour will depend on where and how much of the sphere you cover. In my phot sample I have only covered 1/4 way around, but I finished nearly half way around the sphere in stage 5 photo, next.
