Enamel Canned Spray Paint on interior trim?
Spray painting is fine and generally gives a smoother finish than brush or roller. But you need to fill nail holes, not just paint over the nailheads. Nails should be recessed. Either wood filler or painters caulk should be used in the nail holes. Once the filler is dry, you can spray a q-tip or a piece of paper towel and dab the surface.
