Painting Interior Doors and/or Cabinets
depending on how many cabinets or doors you are doing it would be well worth renting or buying a sprayer. Yes, a roller will leave a smoother finish then a brush. Also even if a roller leaves a texture it is non-directional so is less noticed. But by using a sprayer you will be ale to achieve a smoother finish. Consider if only doing a few doors or cabinets aerosol type spray cans. Cost is high for there coverage but it may be more cost effective the rental if your volume is low. Remember be careful not to put it on to heavy as to run the paint but try and keep a wet edge.
