Day-Glo Paint Collection

Using paints developed by Day-Glo Color Corporation, these blow molds are easily identified (and seen!) by their distinctly bright colors. Poloron Products, Union Products, and later Empire, were the only blow mold manufacturers known to have used Day-Glo paint on their products beginning in the 1960s. By the mid 1970s, Poloron Products, Union Products, and Empire no longer sold products with the vibrant paint, which was often advertised as a way to enhance their daytime appearance.
