Not really - primer is designed to seal and to block staining and to soak into the surface to provide grip, is typically much thinner and less water resistant than a finish paint, and does not have the durable "hide" surface that protects against rain and dirt and mold and such.

Primer should be used just as that - to prime bare materials, or to provide a prep surface on areas that have been sanded or heavily prepared, prior to putting on the finish coats. And with few exceptions, exterior surfaces that have been primed should get two finish coats over the primer initially, then if kept in good shape and not let go so long that the paint starts failing, subsequent repaint coats for several cycles can just be an additional finish coat over a cleaned and (if a glossier than matte finish) perhaps lightly sanded painted surface.
