    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. 

    Autos are painted by mostly robots these days using pretty much
    standard auto paints (acrylic lacquers and other high tech two part
    paints), but the body IS charged elecrostaticly to attract more paint
    particles to the body and reduce overspray. It is then "baked" with
    lamps mainly to speed dry time and to harden the finish. 

    Powder Coat isn't really "paint". Powder Coat is a dry powder ( a
    type of plastic) that is sprayed (dusted) and elecrostaticly clings
    to a item. It is then baked in a oven of sorts (much hotter than a
    auto paint drying booth) into a smooth hard finish. And while it's
    tough, it's not near as tough as chrome as chrome is metal finish.
