Shopping for a car will never be the same as scientists have developed a new form of auto paint that changes color with the touch of a button. This revolutionary new paramagnetic paint is a technical wonder and is viewed by Nissan and other auto companies as an amazing innovation that would draw huge traffic to dealerships and will make it easier for consumers to get the exact option level they want on a car without the sacrifice of their favorite color.

Research with this new science of special light reflecting coatings has been going on for years and there have been several different approaches used to achieve the effect but recent breakthroughs have taken it out of the laboratory and into a real commercial product for large scale applications.

The process starts out with a standard galvanized piece of automotive sheet metal steel. A special polymer is applied to the steel with superparamagnetic iron oxide particles embedded within it. The nanoscale crystalline particles of magnetite (iron oxide) are controlled using a low grade magnetic field which is used to effect the spacing of the colloidal crystals and thereby controlling their ability to reflect light and change color.
