Some users prefer to have a cooker that is other than bright yellow. The ASSC is constructed using "corona treated" polypropylene. While you cannot paint your milk jug, you can paint the ASSC due to the corona treatment. The first paint I tried, Krylon Fusion or Plastic, (available(everywhere) worked very well. Rustoleum also makes and "all surfaces" paint. Just be sure to only paint the outside of the cooker!
