Real Wood vs MDF Molding

Because of the difference in cost many customers have ask me if it is "better to use real wood or MDF moulding".  Believe me you can not tell the difference after it has been caulked, and painted.  Either product will give good service for the life of the home if properly installed.  However; one must use common since when selecting materials even for interior use.  For instance I would not use MDF moulding in areas that are moister prone like baths, kitchens, and garages.   It is best to use real wood in those areas.  So...with that out of the way I would prime both sides of the molding (if it is not already primed) before installation.  This will help to stabilize the moister content of the product.
