    I know that powder coat paint is done this way, but I'm not sure how
    many auto manufacturers are using it, as it is still quite
    expensive. The powder is charged negative or positive (opposite of
    the metal upon which it is deposited), then baked at temperature and
    time until it flows to a smooth finish. Painters on TV shows like
    American Chopper and American Hot Rod describe it as a very hard
    finish that is more like chrome than paint. They do spray it in
    booths, but those booths also have enormous exhaust fans to filter
    out overspray. 

    One thing for sure, any overspray left in the booth would be useless
    as "fordite" as the entire booth would have to be baked in order to
    get the paint to flow out of powder form. But I'm still not sure how
    many are using this type of paint, and I don't think it works with
    other types of paint.
